According to the Admiring Gong Li forum there is still no further news about the filming of "Shanghai" with Li, John Cusack, Ken Watanabe, and Chow Yun-Fat. Last word was that instead of filming in China they would go to the UK and Thailand. Also that it will probably begin filming in May.
The Chow Yun-Fat.de forum recently reported:
"Today several news reports on Baidu say that Chow Yun Fat has either rented or bought a residence in a building at least one hundred perhaps several hundred years old in the Chinese district of Mei Nam Hoi in Thailand. The district is a conservation area, and Fat Go has previously shown great interest in taking photographs there. Perhaps this is related to filming "Shanghai", but no connection is made in the reports......"
