Foreign Minister Wang Yi reiterated requirements from Beijing in Monday’s talks in Tianjin with Deputy Secretary of State Wendy Sherman, namely that the U.S. stop criticizing China’s political system, drop all sanctions and tariffs, and stay out of Hong Kong, Taiwan and Xinjiang affairs.Senior Biden administration officials told reporters afterward that Sherman was focused on setting guardrails on ties, rather than negotiating specific issues. They described the discussions as forthright and professional, even if they were at times tough.The talks in Tianjin — about 60 miles (100 kilometers) east of Beijing — could be the first step toward a meeting between President Joe Biden and China’s Xi Jinping, possibly at a Group of 20 summit in October. “The president continues to believe in face-to-face diplomacy” and expects that will happen “at some point,” White House Press Secretary Jen Psaki told reporters when asked whether the differences aired in Tianjin would prevent a Biden-Xi summit.
