The Seoul city government Monday unveiled a plan to expand three foreigners-only casinos in the nation's capital in a bid to attract more foreign tourists. The city administration will apply to the Ministry of Culture and Tourism for permission to extend the casinos as part of an effort to lure 12 million foreign tourists a year by 2010, city officials said. The three are currently located in the Sheraton Walkerhill Grande Hotel, Millennium Seoul Hilton Hotel and OakWood Premier Coex Center.
