The United Nations Security Council recently unanimously renewed the mandate of the U.N. Assistance Mission in Afghanistan (UNAMA). This was not particularly remarkable in its own right. The council has regularly renewed the mandate for UNAMA since the mission launched in 2002, although discussions of the mandate have become more difficult since the Taliban took Kabul in 2021. What was unusual this year was who led the negotiations on the renewal.
For the first time, China was the uncontested “penholder” — the member state responsible for shepherding the Security Council’s discussions and negotiations – on Afghanistan. This marks a significant shift in Beijing’s approach to council diplomacy. The U.S., France, and the United Kingdom “hold the pen” on multiple files, which gives them the informal power to set the diplomatic agenda on any of those. Russia leads on a couple of issues. By contrast, Beijing historically shied away from taking this responsibility, although it penned a thematic resolution on the safety and security of U.N. peacekeepers in 2020. While there has been much discussion of China’s growing power at the U.N., experts who watch the Security Council have been puzzled that Beijing has refrained from stepping up to act as a penholder on files where it has interests.
Now that it has stepped forward on the Afghan file, its performance guiding the UNAMA resolution offers a window into how China views its ambitions in the multilateral system. It also offers clues as to how Beijing and the United States are cohabiting at the U.N. in the Trump era, as Washington oscillated between complicating and facilitating China’s efforts to nail down the Afghanistan mission’s mandate. The lessons of the process are that China is gaining competence and confidence in U.N. diplomacy — and that the United States is willing to accommodate Beijing’s growing ambitions, although not without caveats.
Claiming the Pen
There was no guarantee that China would secure the role of leading on the Afghanistan mission renewal, or that the United States would acquiesce to this. As we reported in February 2025, China began lobbying other council members in late 2024 to take on that role. Its attention likely stemmed from Beijing’s growing economic interests in the country, a desire to safeguard its national security along the border with Afghanistan, and a more general goal of boosting its profile at the U.N. The UNAMA renewal also may have looked like low-hanging fruit. While the Western veto powers oversee most sensitive council mandates, elected members — most recently Japan — had previously led on the file. Beijing could step into the role when a gap opened up, rather than tussle for the role with other permanent members.
China’s initial push nonetheless faced stiff resistance from the outgoing Biden administration and incoming Trump team. It also had to face down competing claims from two of the Security Council’s elected members, Pakistan and the South Korea. An absurd situation arose in the first quarter of 2025 in which China and Pakistan teamed up to draft a resolution on UNAMA, while Korea and the United States tabled an alternative text. This was solely a matter of status, as the two sides had no significant substantive differences on UNAMA’s role. When the mission’s mandate had to be renewed in March 2025, Denmark — the rotating president of the council that month — stepped in to get a resolution through, leaving the question murky as to who would draft future Afghan-related texts.
The Trump administration changed tack in September, when the United States and China informally negotiated a separate understanding on deploying an anti-gang force to Haiti, which Beijing initially viewed skeptically. The Chinese insisted that the Trump administration — which had been refusing to pay its U.N. dues — stump up some money for blue helmet operations as a quid pro quo for backing the Haiti plan. U.S. Permanent Representative to the U.N. Mike Waltz, who had just arrived in New York, also told China that the United States would drop its objection to leading on the Afghanistan mission renewal, although it is not clear if this was part of the Haiti deal or an extra gesture of goodwill. Korean diplomats, caught off guard by the change in the U.S. posture, could only fume.
Regular watchers of diplomacy at the Security Council focused closely on how Beijing would approach its first experience as a penholder on a prominent country-specific file. The Security Council’s informal working methods encourage penholders to act objectively and prioritize consensus where possible. Chinese diplomats signaled to counterparts that they did not plan anything radical. Security Council diplomats had left the core elements of UNAMA’s mandate untouched since March 2022 out of fear that reopening the text could jeopardize the fragile political consensus underpinning the U.N.’s work in the country. Council members have differed over how to refer to a range of related issues, from engagement with the Taliban, human rights – especially the repression of women — and Afghanistan’s frozen assets. China indicated that it would avoid any controversial changes to the text in 2026. As it turns out, that would prove optimistic, in large part due to U.S. diplomacy.
Trial by Fire
The U.S. mission to the U.N., despite its about-face on the penholding issue, appeared eager to test Beijing’s mettle. U.S. diplomats last December began calling for the Security Council to reevaluate UNAMA’s priorities, asking what the mission could realistically achieve given Taliban-imposed restrictions on its actions. In early March, China circulated a draft text to council members proposing a one-year extension of the UNAMA mandate, unaltered, ahead of a March 17 deadline for renewal. Other diplomats appeared comfortable with this approach, but U.S. officials doubled down on their skepticism towards the mission. They countered China’s proposal with their own, suggestion to renew UNAMA’s mandate for only three months so that diplomats could continue with negotiations.
Beijing appeared unwilling to test whether Washington would veto a longer-term extension of the mandate. The Trump administration had quickly earned a reputation for slashing the budgets of U.N. peacekeeping operations and political offices, including a 15 percent cut to UNAMA that it secured in December 2025. Diplomats speculated whether the United States was interested only in imposing targeted cuts on UNAMA, or if it had its eyes on closing the mission completely.
This uncertainty permeated into the Security Council’s March negotiations, where American officials offered few details about which parts of the UNAMA mandate they wanted to preserve or jettison. Beijing shepherded negotiations on the text’s preamble paragraphs but relented to U.S. pressure and agreed to a short-term mandate renewal. The rest of the council quickly fell in line. Faced with its first real political test as penholder, China opted to protect the council’s consensus on Afghanistan rather than isolate the United States further and potentially jeopardize Washington’s support for the mission.
This compromise bought the council extra time to discuss UNAMA’s future but left Beijing with the task of crafting a new mandate. This was clearly going to require some complicated wordsmithing. The United States aside, council members agreed on the value of the U.N.’s core functions in Afghanistan, including coordinating international assistance, monitoring human rights, and supporting political efforts, and that was the case even if they differed on which tasks the mission should prioritize or consider dropping. However, UNAMA’s existing mandate could clearly benefit from some updates, given that it was cobbled together under pressure in early 2022 in the wake of the Taliban takeover, when the council was still trying to get the measure of the new authorities in Kabul. U.N. officials quietly acknowledged that some parts of the 2022 mandate, such as tasks relating to promoting the rule of law, had become difficult to justify, considering the very narrow or non-existent space the mission had to operate with the Taliban. What began as a burden for Beijing turned into an opportunity for its leaders to show that they could untangle such thorny problems through Security Council diplomacy.
An Evolution in Negotiating Posture
China consulted closely with the other permanent members prior to starting negotiations on the new UNAMA draft. U.S. officials circulated their own position paper outlining proposals to restructure the mandate according to thematic priorities, drop certain tasks on governance and economic assistance, request a new U.N. study (a “strategic review” in U.N. parlance) on whether and how to narrow UNAMA’s tasks, and consider a nine-month mandate, rather than the usual full year. China aligned the structure and length of its initial draft to some of the priorities outlined in the American position paper. This approach reduced the risk that the United States would veto the text, allowing Beijing to disarm Washington of its most credible source of leverage during the rest of the negotiations. (It is worth noting that President Donald Trump visited Beijing in May, while negotiations were ongoing, but we have no information to suggest this significantly affected talks at the U.N.).
Beijing shifted from accommodation to a more impartial broker once it circulated the draft text to all council members. Its new proposal for UNAMA’s mandate reduced the text by half and reorganized the mission’s operative tasks into five streamlined buckets: humanitarian assistance and development, politics, human rights, other issues (such as coordinating explosive ordinance removal), and the mission’s reporting obligations to the council. Most diplomats felt that China’s revisions succeeded in reducing the text without jeopardizing the core of UNAMA’s work. Beijing also accepted a range of inputs from other council members (including on gender and climate, references to the Taliban, and regional integration) often at the expense of promoting its own national positions. Diplomats noted that Russia took a fairly relaxed approach to the process, and avoided pressing its own views on the mandate too hard, most likely as a favor to its Chinese friends.
Getting the text over its final hurdles required China to grow more comfortable with pushing back against select U.S. proposals that neither enjoyed broad support among council members nor appeared to threaten a core U.S. interest. Few states agreed with the U.S. proposal to insert any references to a sunset clause, for instance. China similarly bristled against Washington’s push to shorten the mandate cycle to nine months out of concern that the shorter timeline would weaken the U.N.’s political standing in Kabul and unnecessarily complicate the U.N.’s financial and administrative backstopping to the mission. Beijing calculated correctly that the Trump administration would not go to the mat over such procedural questions, and the United States dropped these requirements.
The final obstacle was how to frame the tasking for the strategic review that the United States had floated. Diplomats signaled some willingness to accommodate the study but balked at U.S. proposals to link the review’s outcome to debates about the mission’s future, potentially setting up a debate about its closure down the line. Chinese officials met bilaterally with council members, including the Americans and Russians, to work out a way to characterize the study that focused on evaluating the UNAMA’s internal operations and coordination, as well as challenges that would impede the mission’s ability to implement its tasks. This compromise opened the way for the council to approve the revised mandate on June 15.
Signs of a Broader Realignment?
Chinese officials were relieved to emerge from the Afghanistan negotiations with UNAMA largely intact. Their approach to the file also allowed them to present themselves as responsible diplomatic citizens. China’s willingness to minimize its own positions on Afghanistan to accommodate the views of other council members reinforced its claims of council unity and consensus. Its willingness to consult early and often with the council’s permanent members stands in sharp contrast to recent U.S.-led negotiations on texts related to Gaza and Haiti, during which U.S. diplomats offered little space for discussion or compromise. The juxtaposition of China’s facilitation style with the approach of the United States is hard to dismiss.
It is not clear whether China will use this experience as a launchpad to pursue larger ambitions inside the Security Council. Beijing’s geopolitical standing and explicit regional interests towards Afghanistan made for a compelling case as to why Beijing would want to take ownership of this council file. It might be less easy for China to make a similar case to take leadership on other issues, especially if that meant asking another veto power to cede the lead. Beijing also needs to keep in mind that the Security Council’s elected members see the entire pen-holding set-up as unfairly limiting their role in council affairs, so China’s efforts to take the lead more often risks diplomatic frictions. There are cases where Beijing does enjoy influence — such as Myanmar –but taking a prominent leadership role in the council could invite criticism of its policies.
The UNAMA negotiations nonetheless show how China is also becoming more calculated in its attempts to balance against a volatile United States at the U.N. The fact that U.S. leadership agreed to let China lead on Afghanistan — and ultimately engaged in transactional diplomacy to finalize the new mandate — suggests that the Trump administration is willing to give China a degree of respect and political space in the Security Council. At a moment when Washington has taken erratic positions towards multilateral cooperation, China has staked out its claim to be a steady mentor for U.N. diplomacy, at least in this particular case. Whether other states buy into that logic more broadly could have a major impact on the Security Council’s ability to forge compromises in the months to come.
