THE Hongkong Association of Business and Professional Women is to solicit support from the business community in a bid to force the Government to introduce the international convention on the elimination of all forms of discrimination against women. Association president Mrs Roberta Wong Leung Kow-won said the body was disappointed by the administration's inaction in extending the convention to the territory despite approval by the Legislative Council when it voted on the issue on December 15. Mrs Wong said her group would gather signatures from the business world this month in a move to dispel the misconception that such an extension would ruin Hongkong's economy. Local and multinational companies would be approached, she said. ''We hope to get several thousand signatures to let the Government know that there is strong support for our demand.'' Mrs Wong was optimistic companies would be willing to sign as none of the legislators representing the business community spoke against the extension during the motion debate last month. There is no time limit for the signature campaign as the association hopes to gather as much support as possible. Mrs Wong accused the Government of not putting much trust in the Legislative Council by not following members' demand for the extension and requesting that the British Government act to add the territory's name to the convention. Instead, the administration decided to publish a Green Paper later this year to consult the public, which was nothing but a delaying tactic to drag out the matter, she said. The association stressed in a recent letter to the Governor, Mr Chris Patten, that: ''If the Government is serious about its desire to extend further democracy to Hongkong, it has to be prepared to accept the will of the Hongkong people as expressed by the Legislative Council. ''It has declared that it will do so over its own proposals for political reform; it has not suggested publishing a Green Paper with regard to these. ''It cannot simply pick and choose which votes it will take note of and which it will ignore.'' Mrs Wong said that if the Government continued to ignore her group's demands, it would bring the issue up at the United Nations Conference on Women to be held in Beijing in 1995. Another women's group, the Association for the Advancementof Feminism, accused Mr Patten of paying lip service to his own promise that he would listen to different views. Spokeswoman Ms Tsang Gar-yin said the association requested a meeting with the Governor more than two months ago but had yet to receive a reply. ''The Governor always says he is open-minded and is willing to listen to various opinions, but what he does is to continue ignoring our demands,'' she said. Findings by an inter-departmental working group studying pay disparity indicated that in 1991 women's median earnings were 78 per cent of men's, while the figure 10 years ago was 69 per cent. The working group claimed the level was the same as in the United Kingdom, which already has equal pay legislation.
