Treasury Secretary Janet Yellen has arrived in Beijing for a four-day visit, the first high-level meeting between the U.S. and China since tensions began to escalate. This visit marks a thaw in ties between the two countries and presents an opportunity to communicate and collaborate on global challenges. Yellen's visit is expected to focus on economic issues, including the global economic recovery, the U.S.-China trade relationship, and the Biden administration's plans for economic stimulus.
