Warren Buffett's annual lunch auction, which is scheduled to end Friday at 7:30pm PST (7:30 am, Saturday BJT), has attracted a number of Chinese investors to bid, the 21st Century Business Herald reported, citing Cecil Williams, organizer of the charity auction.

Williams said that potential bidders from China had contacted him for more information about the auction, but that their names and information were undisclosed.

This year's bidding had reached $900,000 by Thursday evening (PST). Former auctions have shown that bids usually surge in the last few hours before the auctions.

The auctions began in 2000, and at least two Chinese investors have won since then. Duan Yongping, founder of BBK Electronics Corporation, won the 2006 bid at $620,100, and Zhao Danyang, manager of the Pureheart China Growth Investment Fund, won the 2008 bid at $1,680,300.

Reports said the anonymous winners in 2012 and 2013 might also be from China.

Warren Buffett has won large numbers of Chinese fans for his successful investment philosophy.
