GSIC, the Singapore government investment agency and one of the world’s biggest sovereign wealth funds, on Monday announced a management shake-up prompted by concerns about protectionism and regulatory changes in the west. GSIC said it had appointed Lim Chow Kiat to the new post of London-based president for Europe, while Anthony Lim Weng Kin would become president for Americas, based in New York. The changes follow the appointment in June of Lim Siong Guan, a former head of the Singapore civil service, as GSIC group president.
