HANOI, Vietnam (AP) — U.S. Vice President Kamala Harris said Thursday she raised issues of human rights abuses and restrictions on political activism in her conversations with Vietnamese leaders this week, but offered no indication those talks bore fruit.

“We’re not going to shy away from difficult conversations. Difficult conversations often must be had with the people that you otherwise may have a partnership with,” she said at a news conference in Hanoi on Thursday.

Harris said she spoke with Vietnamese leaders in particular about the release of political dissidents, but did not describe the outcome of those conversations. Vietnam has faced criticism for restrictions on freedom of expression and on the press and a crackdown on people it deems political dissidents. But Harris didn't respond when asked why the U.S. criticizes China for similar abuses, but is seeking a stronger partnership with Vietnam.

Her comments capped a weeklong trip to Southeast Asia during which she met with top officials in Singapore and Vietnam in a bid to strengthen U.S. engagement in the region to counter Chinese influence there. Harris unveiled a number of new U.S. agreements and aid for both countries in areas including cyberdefense cooperation with Singapore and coronavirus aid to Vietnam, which is struggling with a new surge in the virus and low vaccination rates.

But on Thursday, she turned her attention to issues surrounding civil liberties and human rights in Vietnam. Harris participated in what her team billed as a “changemakers” event with activists working on LGBTQ rights and climate change.

“It is critical that if we are to take on the challenges we face that we do it in a way that is collaborative, that we must empower leaders in every sector, including of course government but community leaders, business leaders, civic society, if we are to maximize the resources we collectively have,” she said.

In her news conference, Harris also fielded questions on the chaotic U.S. exit from Afghanistan, but did not respond directly when asked how the U.S. would evaluate success in the evacuation mission. Harris also ignored a question on whether Americans are safer now that the U.S. has departed the country. A suicide bomb attack late Thursday — attributed to the Islamic State group’s Afghanistan affiliate — killed at least 13 U.S. service members and many Afghan civilians at the Kabul airport.

On her trip back to Washington, Harris stopped at Joint Base Pearl Harbor-Hickam in Hawaii to meet with servicemembers. She had planned also to stop in California to appear with Democratic Gov. Gavin Newsom, who is facing a recall attempt. But Harris scrapped that stop to head straight to Washington, her office announced.

She has been briefed on developments in Kabul and will continue to be updated as she makes her way back to Washington, the White House said.

While Harris has emphasized that her visit to Southeast Asia is intended to foster a positive relationship with countries in the region and expand U.S. cooperation and involvement, she also ramped up Biden administration rhetoric toward China, issuing repeated warnings to Beijing to end its aggression in the disputed South China Sea.

“We need to find ways to pressure and raise the pressure, frankly, on Beijing to abide by the United Nations Convention on the Law of the Sea, and to challenge its bullying and excessive maritime claims,” she said Wednesday.

Harris avoided the unscripted gaffes that overshadowed her first foreign trip, to Guatemala and Mexico in the spring, where her declaration to migrants — “do not come” — and her flip dismissal of questions about her refusal to visit the border drew criticism from both Republicans and Democrats. Harris took questions from reporters at multiple points that trip, and sat for an extended cable news interview.

In Asia, Harris stayed focused on her meetings with officials and Biden administration talking points on China. While questions surrounding the U.S. withdrawal from Afghanistan dominated her first day in Singapore, Harris emphasized the same message delivered by President Joe Biden and his aides — that the U.S. must remain focused on the evacuations, and not recriminations about what went wrong.
