CHINA'S NBA superstar Yao Ming will play in an exhibition match at the Hong Kong Coliseum early next month. The Houston Rockets' giant, along with compatriot and NBA centre Menk Bateer, will line up for the Chinese national team against Australia's Melbourne Tigers on August 6. It is possible that the Los Angeles Clippers' Wang Zhizhi will also turn out for the mainlanders in a move that would reunite the trio once known as the 'Walking Great Wall' which dominated Asian basketball. The game is part of the government's post-Sars Relaunch Hong Kong campaign. Hong Kong Basketball Association chairman Norman Chan Shui-tim said it would cost the government more than $4 million. Yao was the NBA's No 1 draft pick last year, while Bateer was the second Chinese to play in the world's premier basketball league. The first was Wang, who joined the Dallas Mavericks before being traded to the Clippers. Bateer, who played for NBA champions the San Antonio Spurs last season before becoming a free-agent, signed a two-year contract with the Toronto Raptors last week.
