OSLO: The world’s biggest sovereign wealth fund, Norway’s public pension fund, has divested from Chinese telecom equipment maker ZTE because of corruption fears, the Norwegian central bank which manages the fund said on Thursday. An ethics council that advises the central bank on the fund’s investments said ZTE was facing corruption allegations in 18 countries and the group was or had been under investigation in 10 of them. The Norwegian fund, valued at $820 billion, has as a result sold its entire stake in ZTE. At the end of 2014 the fund held 0.15 per cent of the Chinese group, a stake worth $11.37 million at the time.
