CHINA was yesterday urged to refuse the $4 billion offered by the Government to redevelop defence facilities for use by the People's Liberation Army (PLA) after 1997. ''If China is to accept the $4 billion for the reprovisioning, it is a demonstration to the world that it is acting in breach of the solemn provisions in the Basic Law,'' said United Democrats legislator James To Kun-sun. It would set a bad precedent and might lead to the PLA demanding funding from the post-1997 government, Mr To said. ''If after 1997, we do not have to pay, why do we have to pay on behalf of the Special Administrative Region [SAR] people now?'' Article 14 of the Basic Law stipulated that expenditure for the Garrison should be borne by the central Government, which is responsible for the defence of the SAR. Mr To rejected the Government's ultimatum that all the defence sites would be handed to the PLA after 1997 if the Legislative Council did not approve the Sino-British agreement which was announced on Thursday. ''It is the responsibility on the part of the central Government to release the military sites for other social and economic development if there is no legitimate reason to hold the land,'' he said. Mr To rejected the argument that the payment of $4 billion was acceptable because, in return, 25 sites worth about $65 billion would be released to the Hong Kong Government for redevelopment. The agreement on defence land reached by the Joint Liaison Group after seven years of negotiations saw China get 14 sites totalling 2,750 hectares and Hong Kong 25 sites totalling 139 hectares. The UDHK has not decided whether it will approve the funding request and will seek further explanations in a government briefing on Monday. Independent Andrew Wong Wang-fat said the reprovisioning of military sites should fall outside the definition of defence expenses stated in the Basic Law. Noting that the Government financed reprovisioning for the British Garrison, Mr Wong said the PLA should pay only for its troops and the recurrent cost of the camps. Liberal Party legislator Howard Young said he would recommend that his party support the funding. Commander British Forces, Major-General Sir John Foley said the outcome of the deal was good for Hong Kong and the Garrison was pleased with it as well.
