UPDATE 1-Canada clears Sinopec to buy Syncrude stake

* Sinopec’s move is a benefit to Canada, minister says

* To pay $4.65 billion for stake in oil sands project

WINNIPEG, Manitoba, June 25 (Reuters) - Canada's industry minister said on Friday he cleared China's Sinopec Corp 600028.SS to buy ConocoPhillips' COP.N stake in the Syncrude Canada Ltd oil sands project.

The deal, worth $4.65 billion, is the richest yet for Chinese companies looking for a toehold in the oil sands.

China has made a series of investments in the past year into the northern Alberta oil sands, the largest oil reserve outside the Middle East, as the world’s third-largest economy seeks to lock up energy reserves to power its booming growth.

“I have approved the application by Sinopec ... to acquire control of the ConocoPhillips Partnership because I am satisfied that the investment is likely to be of net benefit to Canada,” Industry Minister Tony Clement said in a statement.

Sinopec, China’s second-largest oil producer and top refiner, agreed in April to buy ConocoPhillips’ 9.03 percent interest in Syncrude -- the largest oil sands project -- with seven other partners controlling the rest. Canadian ownership of Syncrude remains at nearly 56 percent.

ConocoPhillips’ shares on the New York Stock Exchange were down 0.5 percent on Friday
