China Doubles Korea Bond Holdings as U.S. Debt Sold

China more than doubled South Korean debt holdings this year, spurring the notes’ longest rally in more than three years, as policy makers shifted part of the world’s largest foreign-exchange reserves out of dollars.

Korean Treasury bonds held by Chinese investors rose 111 percent to 3.99 trillion won ($3.4 billion) in the first half of the year, data from the Seoul-based Financial Supervisory Service show. China should allocate some reserves to “financial assets in major Asian economies,” Ding Zhijie, a former adviser to China’s sovereign wealth fund, said in an Aug. 16 interview.
