Russian Prime Minister Vladimir Putin travels to China Tuesday for talks likely to focus on a gas deal mired in discord, a day after the two countries signed trade deals worth more than $7 billion. Putin will be accompanied by a 160-member delegation for his two-day visit -- his first abroad since he declared a planned Kremlin comeback -- during which he will meet his Chinese counterpart Wen Jiabao and President Hu Jintao. China's foreign ministry said Tuesday the two countries had already signed 16 economic and trade agreements worth more than $7 billion "in the fields of technology transfer, research and development and mineral development".
