SINGAPORE - Singapore on Thursday stuck to its I8-year ban on the import and sale of chewing gum (口香糖), which has become an international symbol of the city-state's image as a strict society. "The government stands by its decision to ban chewing gum. Chewing gum has not been a significant problem since that ban took effect, there have been concerns that lifting the ban on chewing gum could result in chewing gum litter and weaken ongoing efforts to control littering." Maliki Osman, parliamentary secretary at the Ministry of National Development, told parliament. Osman said as the reason for the imposition (强迫接受) of the ban is still suitable, "the government's position is that the ban shall remain." He was responding to a question in parliament from Denise Phua, a fellow member of the ruling People's Action Party who argued that the ban had been used to criticize its tough governance laws. "I think this ban ... now needs a re-thinking. Surely Singapore will not consider banning sweets because of sweet wrapper litter or ice-cream stick litter," she said. Singapore, known worldwide for its high-quality clean image, banned the import and sale of chewing gum in 1992 in a bid to cope with the problem of people sticking the gum on chairs, tables, lifts and other public areas. One of the key reasons for the ban had been the distce of services on Singapore's subway train system because of chewing gum being stuck on the doors and causing delays. Singapore partially lifted the ban in 2004 by allowing the sale of chewing gum used for health reasons, such as dental health gum, after the conclusion of a US-Singapore Free Trade Agreement. Australian tourist Hazel Lane, 48, said keeping the ban on chewing gum was sure Singaporeans wouldn't want to spoil their "ridiculous" and she told AFP that she's own environment and their own image. Angel Wong, 34, a tourist from Hong Kong, however, welcomed the news. She said, "I come from a country that doesn't have the ban and there's always chewing gum all over the floor, To me the ban doesn't change my image of Singapore so it’s a good thing because it keeps the environment clean." 1.
