FURTHER evidence has surfaced of corporate Hongkong's strong influence on the provincial government in British Columbia. Local companies operating in the province voiced strong concerns about a proposal to levy a corporate capital tax of 0.3 per cent when it was made in April last year. A mounting provincial deficit prompted the proposal for the tax, which would snare companies left profitless by a three-year national recession. But apparently only after a meeting with the Hongkong Canada Business Association did the ruling New Democratic Party indicate its willingness to change its mind on the issue. Now Ms Lucy Shaw Roschat, president of the group and great-grandniece of Sir Run Run Shaw, reports that amendments to the capital tax are planned. Hongkong has a long and prosperous relationship with Vancouver, culminating in, among other things, the largest property project in North America, owned by Mr Li Ka-shing. Investment capital from Hongkong is highly regarded throughout western Canada, so it is no surprise to see the government's economic advisers react so quickly to the tax issue. The association is now seeking changes to the province's new labour laws, which Ms Roschat argues ''make it difficult for employers to make a profit''. But the Hongkong business community in Vancouver will hold its applause for the supposed changes to the capital tax laws until they are printed in black and white. After all, it remains fresh in everyone's minds that New World Development's dream of building a HK$500 million horse-racing track near the city faded in the light of the state government's announcement to proceed with plans of its own.
