Senator Mike Braun of Indiana is warning of China’s playbook to build power though investment in American agriculture.

Braun, a member of the U.S. Senate Committee on Agriculture, Nutrition, and Forestry, issued the warning during a hearing on foreign ownership in U.S. agriculture.

In his remarks, Braun highlighted bipartisan legislation that he introduced in March with three other senators to prohibit the purchase of U.S. farmland by those associated with the governments of Iran, North Korea, China, and Russia.
