Tesco will pay China Resources 4.325 billion Hong Kong dollars ($558 million) for the 20 percent stake in the joint venture. It has an option for an additional 5 percent five years after the deal is done. Some HK$4 billion of the payment will go to China Resources as a special dividend, with the rest to be used as working capital.
The joint venture will operate supermarkets, hypermarkets, convenience stores, cash and carry businesses and liquor stores, as well as online versions of these businesses. It will be the leading retailer in seven of China's eight wealthiest and most populous provinces, Tesco said.
Tesco, which entered China in 2004, has stores in 11 provinces, most of them in the cities of Shanghai and Tianjin and the northeastern province of Liaoning.
The deal is expected to close in the first half of 2014, subject to regulatory and shareholder approval.
China Resources said the tie-up will combine "local customer insights and international retail best practice" and also drive the "internationalization" of China's retail industry.
China Resources is the market leader in the country's highly fragmented supermarket business, with 3 percent share of a grocery market worth 3.8 trillion yuan ($620 billion), according Euromonitor International.
Revenue at the combined business is expected to be nearly 10 billion pounds ($16 billion) a year.
Tesco is the latest of several European and U.S. retailers to suffer a hard landing from dreams of easy riches in China.
Last year, U.S.-based home improvement retailer Home Depot Inc., which entered China in 2006 by acquiring a local chain, closed its seven remaining big box outlets to focus on internet-based sales and specialty stores.
In 2011, U.S. electronics retailer Best Buy stunned customers and employees when it closed all nine of its Best Buy-branded Chinese stores in order to focus on its Five Star outlets, which it acquired through the purchase of a provincial retailer.
The announcement comes as Tesco scales back an aggressive international expansion to refocus on its mainstay U.K. market. The company Wednesday reported that interim net profit fell by about half to 820 million pounds,
"With profits nose-diving in Europe and Asia, the foreign markets that once provided a perfect hedge against weak demand at home are now more hurdle than help," said John Ibbotson, director of U.K. consultancy Retail Vision.
Earlier this year, Tesco beat a retreat from the U.S. by selling off its unprofitable Fresh & Easy supermarket chain. The chain flopped mainly because Tesco opened it just before the start of the economic crisis and misjudged the shopping habits of its target customers. It also said it would leave Japan.
