Both the U.S. and China have played down expectations for the talks in Alaska, which are set to run Thursday and Friday local time. Secretary of State Antony Blinken and National Security Adviser Jake Sullivan will represent the U.S., while Foreign Minister Wang Yi and Politburo member Yang Jiechi will speak for China.

China’s expectations for the meeting aren’t “too high,” Cui Tiankai, China’s ambassador to the U.S., said in comments reported by state-run China Central Television. It will be a success if it starts a “honest, constructive and rational” dialogue, he added.

Both countries have sparred over how to describe the talks, with the U.S. disputing China’s characterization of the meeting as a “high-level strategic dialogue.” Blinken on Wednesday said it will be an opportunity “to very directly, face-to-face, share with our Chinese counterparts the concerns that the United States has, that our allies and partners have about some of the things that China is doing.”

China has urged the Biden administration to remove tariffs and sanctions imposed during Donald Trump’s presidency, as well as measures to restrict sales of key technology to Chinese companies. The Foreign Ministry in Beijing last week said the U.S. “isn’t a reliable country that is to be trusted” after administration officials tightened restrictions on Huawei Technologies Co.

China announced trials would start Friday for two Canadians accused of violating national security laws who were taken in shortly after the December 2018 arrest of Huawei executive Meng Wanzhou, the daughter of company founder Ren Zhengfei. China has often linked the cases to Meng’s, with a Foreign Ministry spokesman telling reporters last year that halting the extradition “could open up space for resolution to the situation of the two Canadians.”

The U.S. and China have sparred over issues such as Hong Kong, Taiwan and Xinjiang in calls since Biden took office, which Beijing has insisted are “internal” issues. But U.S. officials have also sought to stress areas of potential cooperation, including on climate change and nuclear nonproliferation.

White House Press Secretary Jen Psaki told reporters Tuesday that the Alaska meeting wasn’t meant to establish expectations for regular encounters between the two sides.

“I wouldn’t see this as one in a series,” she said. “This is a meeting that our national security adviser and secretary of state are attending, and I wouldn’t build it out beyond there at this point in time.”
