U.S. Treasury Secretary Janet Yellen warns about China's industrial push risking global economic destabilization and diluting green-energy exports. Yellen emphasizes the need to address China's 'massive subsidies' on clean energy products and urges China to tackle overcapacity issues. China's shift towards consumption-led growth is highlighted, with concerns raised about diminishing returns from further investment. Yellen aims to stabilize the U.S.-China relationship and plans to explain the undesirable impact of Chinese subsidy policies during her visit to China.
