A GROUP of university students expressed full confidence in China's future and was determined to enter business in China despite the Xi Yang incident and a series of detentions of businessmen by Chinese officials. At the inauguration ceremony of the Chinese University's China Trade Society, new academic officer Joey Chow Kwok-yin said: ''As a Chinese, I want to contribute to the motherland by doing business there. ''By doing so, we will not only provide employment opportunities for the people there but will also contribute in building up a better economy for the community.'' Joey believed a flourishing Chinese economy could bring about political change in China. ''As China concentrates on its economy which calls for international co-operation, it must also pay attention to problems like human rights and other issues of international concern instead of closing up itself politically.'' ''China is on the right track to market economy and I have full confidence that by 1997, the picture would be more promising,'' Joey said. The China Trade Society, entering its 10th year, aims at promoting China trade and narrowing the gap between the academic and business sectors of Hong Kong society. The society will organise a series of activities including exchange programmes, company visits, seminars and exhibitions, this year on the theme ''Economic and Business Relationship of China, Taiwan and Hong Kong''. Society adviser Law Cheong-kwok said during his speech that Hong Kong's role during China's economic reform was to provide services like transportation and insurance as well as capital for business. New president Priscilla Mok Sau-han told Young Post she joined the society out of concern for the motherland. ''I trust Deng Xiaoping's reforms. We should be practical and boost the economy to improve people's livelihood. And as a university student, our mission is to care about our country.'' Her confidence in China remained strong despite the Xi Yang incident and the detention of several businessmen in China, she added. ''Lack of understanding between the two places could be the cause for such incidents. With a better mutual understanding, such problems could be avoided in the future.'' According to the second year business student, the duty of a student was to learn more about his or her country and its community. ''We should try to achieve this goal through various exchanges and visits to the country,'' said Priscilla. External vice-president Katie Kong Kai-kuen said: ''With the speeding up of reform in China, the political scene will also change. '
