Lima (AFP) - US President Joe Biden and his Chinese counterpart Xi Jinping arrived in Peru Thursday for an Asia-Pacific summit where they will likely meet for the last time under a cloud of diplomatic uncertainty cast by Donald Trump’s election victory.

Air Force One touched down at an air base outside Lima as Xi, who landed hours earlier, was received at the presidential palace by Peruvian leader Dina Boluarte on the eve of a two-day heads-of-state meeting of the Asia-Pacific Economic Cooperation (APEC) grouping.

Biden and Xi are due to hold talks Saturday, in what a US administration official said will probably be the last face-to-face between the sitting leaders of the world’s largest economies before Trump is sworn in in January.

With the Republican president-elect having signaled a confrontational approach to Beijing for his second term, the bilateral meeting will be a closely watched affair.

APEC, created in 1989 with the goal of regional trade liberalization, brings together 21 economies that jointly represent about 60 percent of world GDP and over 40 percent of global commerce.

The summit program was to focus on trade and investment for what proponents dubbed inclusive growth.

But uncertainty over Trump’s next moves now clouds the agenda – as it does for the COP29 climate talks underway in Azerbaijan, and a G20 summit in Rio de Janeiro next week.

On Thursday, APEC ministers, including US Secretary of State Antony Blinken, held their own meeting behind closed doors in Lima to set the tone for the two-day summit to follow.

Trump announced this week he will replace Blinken with Senator Marco Rubio, a China hawk.

- ‘America First’ -

The summit will also be attended by Japan, South Korea, Canada, Australia and Indonesia, among others.

President Vladimir Putin of APEC member Russia will not be present.

Trump’s “America First” agenda is based on protectionist trade policies, increased domestic fossil fuel extraction, and avoiding foreign conflicts.

It threatens alliances Biden has built on issues ranging from the wars in Ukraine and the Middle East to climate change and commerce.

The Republican president-elect has threatened tariffs of up to 60 percent on imports of Chinese goods to even out what he says is an imbalance in bilateral trade.

China is grappling with a prolonged housing crisis and sluggish consumption that can only be made worse by a new trade war with Washington.

But economists say punitive levies would also harm the American economy, and others further afield.

- ‘Criminals and drugs’ -

China is an ally of Western pariahs Russia and North Korea, and is building up its own military capacity while ramping up pressure on Taiwan, which it claims as part of its territory.

It is also expanding its reach into Latin America through infrastructure and other projects under its Belt and Road Initiative.

Xi on Thursday inaugurated South America’s first Chinese-funded port, in Chancay, north of Lima.

He was accompanied for the virtual ceremony by Boluarte, who praised China for playing “a major role in the growth of our economy.”

At the same time, the top US diplomat for Latin America, Brian Nichols, warned in Lima that Latin American nations must be vigilant on Chinese investment.

Biden will on Friday meet Japanese Prime Minister Shigeru Ishiba and South Korean President Yoon Suk Yeol – key US allies in Asia.

Traveling with Biden, National Security Advisor Jake Sullivan said the partner nations will announce the creation of a secretariat to ensure the trilateral alliance “will be an enduring feature of American policy in the Indo-Pacific going forward.”

China isn’t the only country in Trump’s economic crosshairs.

The incoming US leader has threatened tariffs of 25 percent or more on goods coming from Mexico – another APEC member – unless it stops an “onslaught of criminals and drugs” crossing the border.

Peru has deployed more than 13,000 members of the armed forces to keep the peace in Lima as transport workers and shop owners protested against crime and perceived government neglect.
