South Korea’s retirement fund plans to buy more bonds in China and is considering India as it hunts for higher yields in developing nations. The National Pension Service aims to pump some of its 533 trillion won ($487 billion) of assets into China, according to Chief Investment Officer Kang Myoun Wook. It is also looking at putting money into India, where yields are the highest among major Asian nations. The fund, slightly overweight emerging markets for now, is reviewing when to beef up investments further, Kang said.
