What is APEC and which leaders are attending Bangkok summit?

Leaders and heads of governments from the 21 member economies of the Asia-Pacific Economic Cooperation (APEC) have come to the Thai capital Bangkok for a meeting on Friday and Saturday.

As host, Thailand hopes to make progress on discussion of the Free Trade Area of the Asia Pacific (FTAAP), but talks come amid geopolitical tensions over the war in Ukraine and regional flashpoints such as Taiwan and the Korean peninsula.

What is APEC?

APEC is a regional economic forum established in 1989 to promote economic integration. As a grouping, it makes up 38% of the global population, 62% of GDP and 48% of trade.

APEC's 21 members are:

Australia, Brunei, Canada, Chile, China, Hong Kong, Indonesia, Japan, South Korea, Malaysia, Mexico, New Zealand, Papua New Guinea, Peru, the Philippines, Russia, Singapore, Chinese Taipei, Thailand, the United States and Vietnam.

Here is a look at who is attending:

US VICE PRESIDENT KAMALA HARRIS

Harris is standing in for President Joe Biden. The United States will be the APEC host in 2023. After the meeting in Bangkok, Harris will travel to the Philippines. Her visit to the Philippines will be at the edge of the disputed South China Sea, a move that Beijing may see as a rebuke.

CHINA PRESIDENT XI JINPING

Xi met Japanese Prime Minister Fumio Kishida in Bangkok on Thursday for talks. Kishida said he conveyed concerns over regional security to Xi amid growing tensions in Asia over China's maritime ambitions. Xi was quoted by Chinese state broadcaster CCTV as telling Kishida that China and Japan should deepen trust, areas of cooperation and regional integration, and resist "conflict and confrontation".

RUSSIA FIRST DEPUTY PRIME MINISTER ANDREI BELOUSOV

Belousov will represent President Valadmir Putin at APEC. At an earlier APEC meeting in Bangkok this year, representatives from the United States and other countries walked out of a meeting in protest of Russia's invasion of Ukraine when Russian Economy Minister Maxim Reshetnikov was delivering remarks.

JAPAN PRIME MINISTER FUMIO KISHIDA

THAILAND PRIME MINISTER PRAYUTH CHAN-OCHAAs meetings kicked off, Thailand urged APEC members to "rise above differences" after geopolitical tensions dominated summits in Bali and Phnom Penh over the war in Ukraine.

CANADA PRIME MINISTER JUSTIN TRUDEAU

China's leader appeared to confront Trudeau at the G20 summit in Bali on Wednesday after accusing him of leaking details from a closed-door meeting, a rare public display of annoyance by Xi. China's foreign ministry on Thursday said Xi was not criticising Trudeau over the alleged leaks.
