Singapore’s GIC and OCBC’s insurance arm have joined a group led by US private equity firms KKR (KKR.UL) and TPG (TPG.UL) that is buying Morgan Stanley’s (MS.N) 34.3 percent stake in top Chinese investment bank CICC.

Reuters Breakingviews late on Wednesday reported that the Government of Singapore Investment Corp (GIC) (GIC.UL), Singapore’s sovereign wealth fund, and another unnamed investor had joined the bid by KKR and TPG for Morgan Stanley’s stake.

Bloomberg reported on Thursday that another member of the buyer group was Singapore’s Great Eastern Holdings Ltd, the insurance company controlled by Overseas Chinese Banking Corp (OCBC).

Morgan Stanley has been trying to sell its stake in China International Capital Corp (CICC) for several years now, and indicated as early as 2007 its intent to form a new investment banking joint venture with China Fortune Securities.
