MOSCOW, Oct. 20 (Xinhua) -- The reciprocal Russia-China theme years, held in the two states since 2006, have contributed to the growth of bilateral relations, ranging from political to economic and cultural spheres, said a senior Russian diplomat on Friday.

"In fact, the project embraces all spheres of the Russian-Chinese relations: summit and high-ranking contacts, trade, economic and humanitarian cooperation, and inter-regional contacts," said Konstantin Vnukov, director of the Foreign Ministry's First Asian Department.

More than 200 events were held in the Year of China in 2007, which strengthened the Russian-Chinese friendship, he said, adding that Presidents Vladimir Putin and Hu Jintao have "lauded the project and agreed to make regular some of the most interesting events."

"The main goal of the project has been achieved - the social foundation of Russian-Chinese friendship has broadened, and the countries' images have improved in the eyes of the Russian and Chinese public, especially young people," he noted.

Commenting on the soaring bilateral trade and economic ties, Vnukov predicted that Russian-Chinese trade could reach 60 billion U.S. dollars in 2010.

"There is reason to believe that a 60 billion U.S. dollars landmark, designated by the leaders of the two nations, will be exceeded by 2010," he said, noting bilateral trade will top 40 billion U.S. dollars this year.
