Vice President Kamala Harris arrived in Thailand on Thursday, part on a weeklong trip to Southeast Asia, just as President Joe Biden was concluding his own visit to the region.

Harris is visiting Thailand and the Philippines, where she will attend events for the Asia-Pacific Economic Cooperation, meet with world leaders, participate in discussions on climate change and empowering women and girls, and make a historic visit to a Philippine island.

“The vice president will make clear that the United States has an enduring commitment to Southeast Asia,” a senior administration official told reporters Tuesday. 

The combination of Biden’s and Harris’ visits to the area “shows the deepening of our engagement in this region and the effort by both the president and the vice president to strengthen our alliances in the region and to invest in critical institutions,” the official said.

After attending the United Nations climate summit in Sharm El-Sheikh, Egypt, Biden visited Cambodia and Indonesia, which hosted the annual G20 summit. He was flying back to the United States on Wednesday.

Harris and second gentleman Doug Emhoff will arrive in Bangkok on Thursday. The vice president, who visited Singapore and Vietnam last year, will attend the APEC leaders retreat Friday and Saturday. There, she will “reaffirm our economic leadership in the region,” the senior administration official said.

She will also make proposals for “key principles we think should guide APEC economies and rally other economies around our vision for the future of the rules-based international economic order,” the official said.

Also Friday, she will deliver a speech at APEC’s CEO summit. 

“The central message of her remarks will be that the United States has an enduring economic commitment to the Indo-Pacific, and there is no better partner for the economies and companies of the Indo-Pacific than the United States of America,” the official said.

“We believe it’s important to show our track record — everything we’ve done and are going and will do. And this includes our increased diplomatic engagement in the region.”

Harris and Emhoff will then attend an audience with King Maha Vajiralongkorn Phra Vajiraklaochaoyuhua and Queen Suthida Bajrasudhabimalalakshana at the Grand Palace.

On Saturday, the vice president will hold a bilateral meeting with Thai Prime Minister Prayut Chan-o-cha.

“She’ll underscore our enduring commitment to Thailand and the work to strengthen our alliance,” the administration official said.

“The focus will be to deepen bilateral cooperation on areas such as the climate crisis and economic development by accelerating the clean energy transition, building climate resilience, and promoting sustainable development.”

On Sunday, Harris will host a roundtable discussion with environmental and clean energy leaders to discuss the impacts of climate change on communities that depend on the Mekong region and the U.S.’s work on climate change and economic development in the region.

Harris and Emhoff will fly to Manila, Philippines later Sunday.  

On Monday, the vice president will meet with Philippine Vice President Sara Duterte-Carpio before holding a longer bilateral meeting with President Ferdinand Romualdez Marcos Jr.

“The focus with President Marcos will be twofold: strengthening our security alliance and economic relationship,” the senior administration official said.

Also Sunday, the vice president will participate in a moderated conversation at the University of Santo Tomas about empowering women and girls.

“As she does all around the world, the vice president prioritizes lifting up the voices of women and advocating for their economic empowerment and civic participation,” the administration official said. “This will be the first event of its kind she has done overseas since taking office.”

Then Tuesday, Harris and Emhoff will fly to the province of Puerto Princesa, Philippines, on the island of Palawan, where she will meet with residents, civil society leaders and representatives of the Philippines Coast Guard.

Harris will become the highest-ranking U.S. official ever to visit Palawan.

“The vice president feels very strongly about getting outside of government buildings and engaging directly with people who often don’t get to interact with high-ranking U.S. officials,” the senior administration official said. “Leaving the capital city and going to Palawan and visiting communities there will do just that.”

Harris and Emhoff will depart the Philippines later Tuesday and land in Los Angeles on Wednesday.
