U.S. Treasury Secretary Janet Yellen traveled to China on Monday.
China's production “overcapacity” was at the heart of Yellen's trip. The United States fears that the Chinese government's massive subsidies in technologies will lead to a tidal wave of low-cost products around the world. Yellen also said she had "difficult conversations about national security," warning Chinese officials about the consequences of providing military support to Russia and resorting to economic measures in the name of national security.
