Kuala Lumpur, Malaysia, Oct 25 (AP) Southeast Asian foreign ministers open talks Saturday ahead of a landmark ASEAN summit that will formally welcome East Timor as the bloc's 11th member and mark U.S. President Donald Trump's first trip to Asia since returning to the White House.

The meeting serves as a curtain-raiser for the annual Association of Southeast Asian Nations summit which starts on Sunday in Kuala Lumpur, followed by two days of high-level engagements with key partners including China, Japan, India, Australia, Russia, South Korea and the U.S.

Leaders are expected to focus on regional security, economic resilience, and maritime disputes — with U.S. tariffs and shifting global trade patterns looming large over discussions.

A separate leaders summit of the Regional Comprehensive Economic Partnership — the world's largest trade bloc encompassing ASEAN and five partners: China, Japan, South Korea, Australia, and New Zealand — will convene for the first time since 2020.

Its revival comes as regional economies seek to stabilize trade flows at a time when Washington's tariff measures have rattled markets and tested decades of globalization.

Apart from Trump, Chinese Premier Li Qiang and Japan's newly inaugurated Prime Minister Sanae Takaichi are among more than a dozen leaders attending the ASEAN summit and related meetings.

Brazilian President Luiz Inácio Lula da Silva and South African President Cyril Ramaphosa will also participate as new sectoral dialogue partners — part of Malaysian Prime Minister Anwar Ibrahim's effort to deepen ASEAN's economic ties with Africa and Latin America.

Trump's return to Asia Trump's trip marks his first ASEAN meeting since 2017 and his first journey to Asia in his second term. The last U.S. president to attend an ASEAN meeting was Joe Biden in 2022.

Officials say Trump is expected to witness new U.S. trade deals, including with Malaysia.

Trump is also expected to preside over the signing of an expanded ceasefire between Thailand and Cambodia, following border clashes between the countries earlier this year. The ceasefire deal was brokered in Kuala Lumpur in July with ASEAN's support and under Trump's threat to suspend trade negotiations.

“Trump's presence reflects a rare moment of direct U.S. presidential engagement in the region,” said Joanne Lin, co-coordinator of the ISEAS–Yusof Ishak Institute's ASEAN Studies Centre in Singapore. It signaled Washington still sees value in ASEAN as part of its Indo-Pacific outreach, she said.

“But more than deepening U.S. involvement, this visit is about visibility. Trump wants to project himself as a global dealmaker at a time when his domestic policies, especially tariffs, have unsettled key partners in the region,” Lin said.

Tight security in Kuala Lumpur Security has been ramped up across Kuala Lumpur ahead of planned protests against Trump's visit, particularly over his administration's stance on the Palestinian issue.

Anwar has said the government would allow peaceful demonstrations but vowed the meetings would proceed smoothly. While Anwar acknowledged that some critics may have called Trump anti-Muslim, Anwar commended Trump for helping broker a ceasefire in Gaza “which is near impossible under normal terms.” Malaysia, however, maintains that the truce has not resolved the Palestinian question and intends to raise the issue directly with Trump during the summit, Anwar said.

East Timor joins ASEAN This year's summit marks a milestone for ASEAN as it welcomes a new member for the first time in 26 years. It has been a long but rewarding journey for East Timor, also known as Timor Leste, which applied for membership in 2011. The last member to join ASEAN was Cambodia in 1999.

The integration of the region's youngest and poorest nation — with just 1.4 million people — is being hailed as a symbolic step for regional inclusivity. East Timor was a Portuguese colony for over four centuries before Indonesia's 1975 invasion.

A brutal 24-year occupation followed, claiming tens of thousands of lives through conflict, famine and disease. A U.N.-supervised referendum in 1999 paved the way for independence, which was formally restored in 2002.

ASEAN membership gives East Timor access to the bloc's free trade deals, investment opportunities and a broader regional market — vital for diversifying an economy long reliant on oil and gas.

“They are poor, yes, but they still have the potential. As a community, it's our duty to prop up these countries,” Anwar has said.

Regional tensions and the Myanmar crisis Leaders are also expected to discuss flashpoints including the South China Sea dispute, Myanmar's civil war, and the spread of cross-border scam networks.

During the meetings, ASEAN will sign an upgraded free trade pact with China and continue negotiations on a long-delayed code of conduct for the contested waterway.

Meanwhile, the civil war triggered by Myanmar's 2021 military takeover continues to test ASEAN's unity, with military government leaders still barred from summits after failing to comply with the bloc's 2021 Five-Point Consensus on peace and dialogue. Myanmar's plans for elections in December — dismissed by critics as neither free nor fair — have put the bloc in a tight spot and will be discussed at the summit.

The military government has invited ASEAN nations to send election observers, but accepting could be seen as legitimizing the regime, while refusal risks further isolating Myanmar and weakening ASEAN's leverage.

“The bigger question is what happens after the vote: whether ASEAN will continue to disinvite Myanmar's political representatives from future summits if the junta claims legitimacy through this election,” Lin, the Singapore-based analyst, said. (AP) HIG HIG

ASEAN membership expansion grants East Timor trade access and raises obligations for regional economic and security governance. ASEAN's admission of East Timor confers access to the bloc's free trade arrangements and investment frameworks while obliging alignment with ASEAN economic governance. Summit outcomes emphasise multilateral trade governance-revival of RCEP and an upgraded pact with China-and use of diplomatic instruments, including trade deals and a summit-witnessed ceasefire. Security priorities focus on negotiating a Code of Conduct for maritime disputes and addressing the Myanmar crisis, where compliance with the Five-Point Consensus and the legal implications of election observers pose challenges to ASEAN's normative cohesion.
