In the meantime, CITIC Pacific continued its aggressive expansion. With sales topping HK$10 billion for 1993, the company paid HK$3.06 billion (US$390 million) for a 50 percent share of a residential development on Hong Kong's Discovery Bay island. The company was also active on the infrastructure front, paying HK$104 million (US$13.3 million) for 25 percent of the Western Harbour Crossing, a tunnel project linking Hong Kong with the territory's Kowloon airport. The company also acquired 28.5 percent of another Hong Kong tunnel project, the Eastern Harbour Crossing, as well as gaining 50 percent of a mainland tunnel, in Shanghai. These moves were also seen as part of CITIC Pacific's attempt to counter criticism that the company was still not much more than a holding company for passive investments. The company slowed its acquisition growth to concentrate on taking a more active management role in the tunnel projects and its Hang Chong subsidiary. Revenues continued to grow, topping HK$12 billion in 1994. The diversity of CITIC Pacific's projects, which by then included a joint-venture with Japan's Isuzu to build cars and light trucks on the mainland, as well as a 20 percent stake in a joint venture to build an airport railway system, seemed to have finally elevated the company to true hong status.
