Foreign ministers of ASEAN countries convened in Kuala Lumpur on July 9, 2025, amid rising tensions and global power rivalries. The gathering also saw China’s pledge to join a regional ban on nuclear weapons. At the same time, U.S. Secretary of State Marco Rubio and Russia’s Sergey Lavrov held rare talks on the sidelines of the summit.

The ASEAN gathering is unfolding under the cloud of President Donald Trump’s aggressive tariff strategy, which threatens to upend regional economies and U.S. alliances. The new U.S. trade measures, set to take effect on August 1, include a 25 percent tariff on Malaysia, 32 percent on Indonesia, 36 percent on Cambodia and Thailand, and 40 percent on Laos and Myanmar.

Even key American allies like Japan and South Korea have not been spared, both slapped with 25 percent tariffs. Australia has been threatened 200 percent duty on pharmaceutical exports to the U.S.

Only two countries have managed to secure separate trade agreements with the Trump administration: Vietnam and the United Kingdom. Under the new deal, the U.S. will impose a lower 20 percent tariff on many Vietnamese exports, and Vietnam will eliminate tariffs on U.S. products. However, transshipments through Vietnam from third countries will still face a 40 percent tariff, Trump warned.

With trade uncertainty mounting, ASEAN countries have begun pivoting toward alternative partners, particularly China. “These tariffs have provided an impetus for all of these ASEAN nations to seek out closer trade links with other parts of the world,” said a diplomat attending the summit.

Tensions in Myanmar

Beyond economic and geopolitical challenges, the ASEAN summit also addressed pressing humanitarian concerns. A draft joint communique to be released by ASEAN foreign ministers expressed “concern over rising global trade tensions and growing uncertainties in the international economic landscape, particularly the unilateral actions relating to tariffs.”

Another draft statement condemned violence against civilians in Myanmar, where a civil war has raged since the military coup of 2021. ASEAN has taken the lead in mediating among the fractured factions, though its success has been limited.

China backs ASEAN nuclear ban treaty

China has confirmed its intention to sign the Southeast Asian Nuclear Weapon-Free Zone (SEANWFZ) treaty, a landmark move signaling its willingness to align with the region’s desire to remain shielded from the increasing threat of nuclear escalation.

Host of the summit and Malaysia’s Foreign Minister Mohamad Hasan told reporters on Thursday that China had formally committed to the treaty. “China committed to ensure that they will sign the treaty without reservation,” he said, adding that the formal signing would occur once documentation is finalized.

The SEANWFZ treaty, which entered into force in 1997, prohibits the development, manufacture, acquisition, or testing of nuclear weapons within the region. Though all ASEAN member states are signatories, none of the five recognized nuclear-armed powers, the United States, China, Russia, France, and the United Kingdom, have signed on. ASEAN has consistently called for these countries to respect the region’s non-nuclear status, including its continental shelf and exclusive economic zones.

Beijing’s decision comes amid a broader geopolitical recalibration. Just last week, China hinted at its readiness to support the treaty as a gesture of leadership among nuclear states, a signal welcomed by ASEAN members increasingly wary of rising tensions between Washington, Moscow, and Beijing.

Rubio and Lavrov talk on the sidelines

Amid these economic concerns, high-stakes diplomacy is also taking place on the sidelines. U.S. Secretary of State Marco Rubio and Russian Foreign Minister Sergey Lavrov held rare face-to-face talks in Kuala Lumpur, discussing the ongoing war in Ukraine, as well as developments in Iran and Syria.

“A substantive and frank exchange of views took place on the settlement of the situation around Ukraine, the situation around Iran and Syria, as well as several other international issues,” Russia’s Foreign Ministry said in a statement following the meeting.

Lavrov and Rubio reportedly confirmed their “mutual desire to find peaceful solutions to conflicts, restore Russian-American economic and humanitarian cooperation, and facilitate unimpeded contacts between the societies of the two countries.”

Rubio, speaking after the 50-minute meeting, said he had delivered a clear message: “We need to see a roadmap moving forward about how this conflict can conclude.” He added that President Trump remains frustrated with Russian President Vladimir Putin, accusing him of blocking serious diplomatic progress. “Putin was throwing a lot of ‘bullshit’ at U.S. efforts to end the war,” Trump was quoted as saying earlier this week.

Rubio’s visit, his first to Asia as secretary of state, reflects Washington’s renewed attention to Southeast Asia following years of focus on conflicts in Europe and the Middle East. His mission includes reassuring jittery allies that the U.S. remains committed to the region, both economically and strategically.

“Many ASEAN members are traditional allies of the United States,” a senior diplomat noted. “But they are somewhat nervous about the tariffs and recent U.S. foreign policy moves. Rubio is here to reassure them that all is well in trans-Pacific relations.”

In contrast, China’s Foreign Minister Wang Yi has also been working the diplomatic corridors in Kuala Lumpur, holding bilateral meetings, and reinforcing Beijing’s message of partnership and shared development. Russia’s Lavrov has been advocating for a “multipolar world order”, a concept embraced by Beijing and seen by ASEAN diplomats as a challenge to U.S. global dominance.

Opportunity amid uncertainty

With the ASEAN region now a battleground for influence among global powers, it finds itself in a paradoxical position. On one hand, economic pressures are intensifying, particularly from Washington’s tariffs. On the other hand, ASEAN is leveraging its centrality to push for commitments like the nuclear ban and gain concessions from powerful partners.

The presence of high-level U.S., Russian, and Chinese diplomats in Kuala Lumpur reflects not only ASEAN’s strategic significance but also the urgent need for dialogue in an increasingly polarized world.
