According to PetroChina, it held a 100% interest in Sun World which directly held 2.51 billion shares in CNPC Hong Kong, representing approximately 56.66% of the total issued share capital of CNPC Hong Kong.

The percentage of interest owned by PetroChina in CNPC Hong Kong has increased from approximately 51.89% as on the date of the sale and purchase agreement to 56.66%, as on the date of this announcement due to a series of share repurchases by CNPC Hong Kong of its 415.57 million shares since September 9, 2008, said the company.

After the acquisition, PetroChina will become a controlling holding company of CNPC Hong Kong, which is expected to reduce its competition with its controlling shareholder CNPC.
