REUTERS/Shelby Tauber/File PhotoWASHINGTON/DAVOS, Switzerland, Jan 16 (Reuters) - U.S. Treasury Secretary Janet Yellen will meet Chinese Vice Premier Liu He in Switzerland on Wednesday to exchange views on economic developments and deepen communication between the world's two largest economies, a Treasury official said. Yellen and Liu will also discuss global challenges like the possibility of a world recession, the corresponding risks, and how to enhance cooperation, the official said. Yellen does not plan to attend the World Economic Forum. Yellen has met virtually three times with Liu since taking office, and met in Bali, Indonesia with Chinese central bank governor Yi Gang. Liu will step down this year as part of an overhaul of China's economic leadership disclosed in September.
