China Resources Beer (Holdings) Co will soon ask investment banks to pitch for a role advising on options for its Chinese brewery joint venture with SABMiller Plc, people with knowledge of the matter said.

The State-backed company is seeking advisers as it weighs a potential purchase of all or part of SABMiller's 49 percent stake in China Resources Snow Breweries Co, the maker of Snow, the world's best-selling beer, the people said. China Resources has told banks it will send out a formal request for proposals as early as this week, the people said, asking not to be identified as the information is private.

Anheuser-Busch InBev NV may need to sell the stake in the brewer of Snow lager to secure Chinese antitrust approval for its 73.5 billion pound ($110 billion) acquisition of SABMiller, which will create a beermaker controlling about half the industry's profits. SABMiller's stake in the Chinese venture could fetch as much as $3.6 billion, Nomura Holdings Inc wrote in a research report.

"China Resources has already learned enough from SABMiller about how to operate a beer factory effectively and now can manage it by itself," Charlie Chen, an analyst in BNP Paribas SA in Hong Kong, said on Monday.

"China Resources may buy the stake with another Chinese local beer firm."

Shares of SABMiller reversed earlier losses to close up 0.1 percent at 40.315 pounds in London on Monday. China Resources shares rose 0.133 percent to HK$15.1 ($1.95) at close on Tuesday in Hong Kong.

China Resources aims to pick advisers by the end of the year, the people said., adding AB InBev has not yet decided whether it will sell the stake, and China Resources is not set on any particular course of action.

Several banks have reached out to China Resources in recent weeks to offer financing for any potential buyout of the Snow joint-venture stake, according to the people. They said China Resources is seen as the logical buyer if AB InBev decides to sell, as it has a right of first refusal.
