BEIJING/ WASHINGTON, March 30 (Reuters) - China on Thursday called remarks by U.S. Treasury Secretary Janet Yellen "irresponsible" and "unreasonable" after Yellen said Beijing's lending activities leave developing countries "trapped in debt." Yellen on Wednesday said she was concerned by some of China's activities globally, particularly its lending to developing countries. "We do not accept unreasonable accusations from the United States," Chinese Foreign Ministry spokesperson Mao Ning said in a news briefing on Thursday. "The United States should take practical actions to help developing countries, instead of pointing fingers at other countries and making irresponsible remarks," Mao added. China says it has always followed international rules and carried out investment and financing cooperation with developing countries with openness and transparency.
