ULAN BATOR, Feb. 12 (Xinhua) -- The biennial Mongolia-China expo is a great opportunity for Mongolia to diversify its exports to China and expand bilateral economic and trade ties, a senior Mongolian official has said.

"We are now cooperating with the Chinese side to organize the third Mongolia-China expo in Hohhot, capital of China's Inner Mongolia Autonomous Region, in September," Tuvshintugs Battsetseg, deputy director of the Department of Foreign Trade and Economic Cooperation at the Ministry of Foreign Affairs of Mongolia, recently told Xinhua.

China has been Mongolia's biggest trading partner and top export market destination for almost two decades, and mining products have accounted for the majority of the Mongolian total exports, she said.

"Our country is willing to diversify its exports to China or increase the exports of non-mining sectors," she said.

Mongolia and China have set a 10-billion-U.S.-dollar target for bilateral trade by 2020, she said, expressing her hope that the biennial event will play a major role in achieving the target.
