BEIJING, Nov. 26 -- China and Bulgaria vowed on Thursday to deepen their cooperation in areas including infrastructure, nuclear power, agriculture and tourism.

The pledge came out of a meeting between Chinese Premier Li Keqiang and visiting Bulgarian Prime Minister Boyko Borissov after Tuesday's annual leaders' meeting between China and the countries of Central and Eastern Europe (CEE) in Suzhou, Jiangsu Province.

Li said China is willing to participate in infrastructure construction programs for high-speed rail and highways around the Black Sea proposed by Bulgaria, adding that the two sides will also discuss cooperation on nuclear power, agricultural products and tourism.

The friendship between the two countries is profound, and bilateral relations are healthy and stable, Li said, adding that as an important CEE country, Bulgaria plays a positive role in China-CEE cooperation.

China values relations with Bulgaria and hopes to increase exchanges between the two countries and promote a friendly, comprehensive partnership, he said.

Congratulating the annual leaders' meeting between China and CEE countries on its success, Borissov said Sino-Bulgarian relations are solid and the two sides are willing to enhance cooperation in railway and highway construction as well as nuclear power.
