GUANGZHOU, China (AP) — U.S. Treasury Secretary Janet Yellen said that the U.S. and China had agreed to hold talks that will address a key American complaint about China’s economic model. The agreement came on the second day of an official visit to China during which Yellen has appealed to Chinese leaders to change their domestic manufacturing policies. Yellen started her five-day visit in Guangzhou and has focused the trip on what the U.S. considers to be unfair Chinese trade practices. The official Xinhua News Agency said that the two sides had agreed to discuss a range of economic and financial issues; and, without details, that China had responded fully on the issue of production capacity.
