CHINA has urged Britain to solve the boat people problem before the handover, saying it has an obligation to do so. Ambassador Zhao Jihua , leader of the Chinese side in last week's Joint Liaison Group talks in London, said he had urged Britain to take more action. He did not want the Viet issue to be a burden for the SAR government. Despite some progress during the three days of talks, it was clear both sides had grievances over delays. The principal area of contention remained the right of abode issue. Hugh Davies, head of the British side, said 95 per cent of all right of abode issues had been resolved. It is understood the major remaining difference is over China's desire for the provisional legislature to agree to the terms for right of abode and pass a law so it can be defined before the handover. But it appears China is prepared to stall on this, with Mr Zhao insisting right of abode is an 'internal matter'. There will be one full plenary session of the JLG before the handover, but Mr Zhao said agreement on the issue could be reached before then.
