Meanwhile, the company continued to refocus its business, turning away from minority investments and investing its war chest instead into a new string of infrastructure deals, including a US$200 million purchase of 45 percent of Shanghai's Xu Pu Bridge. The company also added to its infrastructure portfolio with controlling interests in another two mainland power stations. In real estate, the company purchased, for HK$3.5 billion, the former British naval headquarters site in Central Hong Kong's Tamar Basin in order to build the company's 37-story headquarters, expected to be completed in 1998.
