China National Petroleum Corporation (CNPC) will further enhance its cooperation with Canadian petroleum sector, a spokesman with the China's largest oil producer has said.

This announcement on Friday came as local newspapers in Canada have reported that a senior executive of CNPC said at a conference in Canada that CNPC would pull out from an oil sands project due to lack of backing from Canadian government and producer.

"It is just personal opinion and cannot represent CNPC's standpoint," said an internal person with CNPC.

"CNPC will continue to be positive in cooperating with Canadian counterparts in oil sands development," the spokesman said without commenting the reported oil sands project.

"Since the 1980s, CNPC has carried out extensive exchanges and cooperation with Canadian petroleum sector," according to the circular released by CNPC in the name of a spokesman.

Starting from the early 1990s, CNPC has registered an oil and gas exploration and development company in Alberta and awarded interests of eight blocks in Provinces of Alberta and Saskatchewan.

CNPC has been always holding a proactive attitude towards cooperating with Canadian counterparts in oil sands, including oil sands development, pipeline transportation, trading and technology exchanges and the company has made an extensive study in terms of oil sands resources, market and technology, said the spokesman.

CNPC has acquired 11 oil sands leases auctioned by provincial government of Alberta early this year, according to the company.
