BEIJING, March 2 (Reuters) - Shanghai Guosheng Group, a portfolio and investment agency controlled by the Shanghai municipal government, has taken over the management and daily operations of CEFC China Energy, the South China Morning Post (SCMP) reported on Friday.
The reported move comes after Ye Jianming, the chairman of CEFC, the private firm that has agreed to buy a nearly $9.1 billion stake in Russian oil major Rosneft, was investigated for suspected economic crimes, according to a source briefed on the matter.
The SCMP report cited two unidentified sources with direct knowledge of the matter.
Responding to the report, a CEFC spokesman said that the company has not been informed of any takeover and that CEFC China Energy management continues to run the company.
Shanghai Guosheng did not answer calls seeking comment.
CEFC disputed the reports that Ye was being investigated, saying in a statement issued late on Thursday that they "had no basis in fact" and that the company was "operating normally."
The company appears to be the second in the past week to be seized by the Chinese government as Beijing aims to curtail big-spending conglomerates in a crackdown on financial risk.
Last Friday, the Chinese government took control of Anbang Insurance Group Co Ltd and said its chairman had been prosecuted for economic crimes.
Other conglomerates with major overseas assets have also come under government scrutiny in recent months, buffeted by shifting policy winds. These include HNA Group, the parent of Hainan Airlines, Dalian Wanda, Fosun and others that had once enjoyed government support and encouragement to invest abroad.
Set up in 2007, Guosheng is an investment arm of the Shanghai government.
It has invested in state-owned Commercial Aircraft Corp of China Ltd, or COMAC, and holds stakes in a range of other state firms, including Bright Food and Guotai Junan Securities.
Part of its remit is to "promote the integration and reorganisation of various resources, capital and assets" and "actively participate in the reorganisation and adjustment" of state-owned assets and enterprises, according to its website.
