Chinese government is expected to inject up to 10 billion yuan (1.25 billion US dollars) into China Reinsurance, the country's top reinsurer, to help it compete with foreign rivals, Reuters reported, citing market sources. Central Huijin, the investment arm of the central bank, has submitted a proposal for the capital injection to the State Council. The plan could win approval before the end of this year, Reuters quoted the sources. After approval, the central bank and China's foreign exchange regulator would authorise Central Huijin to use part of the country's more than $940 billion in foreign exchange reserves as capital for China Reinsurance, the sources said. The injection would be the first time that China used its fast-growing foreign exchange reserves to inject capital into an insurance company.
