Yellen In China Calls For 'Level Playing Field' For US Firms

US Treasury Chief Janet Yellen called on Friday for a "level playing field" between American and Chinese companies, telling officials during a visit to southern China that Beijing's industrial subsidies threatened that balance.

Yellen arrived in the city of Guangzhou on Thursday for four days of talks with Chinese officials on what is her second visit to the world's number two economy in less than a year.
