Chinese researchers tour Iowa farm

The United States' best-known farm in China, Kimberley Farms in Iowa, received a group of leading think tank researchers from Beijing for the first time on Sunday, after becoming an attraction for Chinese visitors since President Xi Jinping's visit five years ago.

Nearly 20 members of top Chinese think tanks, including the Chinese Academy of Social Sciences and China Center for International Economic Exchanges, retraced the roads that Xi traveled in 2012 as a visiting vice-president.

They ended the tour with a field trip to patches of the 1618-hectare corn and soybean farm operated by Rick Kimberley in Maxwell, Iowa, about 60 kilometers northeast of the state capital Des Moines.
