US Treasury Secretary Janet Yellen has kicked off her second visit to China to continue efforts to further stabilize ties between the world’s two largest economies. On her first full day of meetings in Guangzhou, Yellen said Friday she would address the oversupply of Chinese goods in key industries, such as electric vehicles (EVs) and solar panels. "I will stress that a healthy economic relationship can bring significant benefits for both our economies," she said at a meeting with leaders of Guangdong province, the country’s manufacturing powerhouse. "At the same time, I’ve also emphasized that building a healthy economic relationship requires a level playing field for American workers and firms, and open and direct communication on areas where we disagree," she said, noting that China’s industrial overcapacity and its global spillovers are causing concerns in the United States and other countries.
