The chief trade negotiators of the United States and the European Union will visit Beijing this month for talks with Premier Zhu Rongji to clear obstacles to China's entry into the World Trade Organisation, according to diplomats. The WTO working group on China met for three weeks in Geneva last month with the aim of tidying up the loose ends of Beijing's entry. It has concluded bilateral talks with all 137 members of the WTO except Mexico. 'The meeting achieved nothing,' said one European diplomat. 'At the end, China's chief WTO negotiator Long Yongtu lost his temper and the head of the working group threatened to resign. 'As a result, the EU and the US decided to send their chief trade representatives here to meet Mr Zhu and find a political solution to the remaining obstacles, which are the details of the agreements the two signed with China.' China signed an agreement with the US on its WTO accession in November and with the EU in May. The meetings, involving Charlene Barshefsky of the US and Pascal Lamy of the EU, are likely to take place after the end of China's National Day holiday which runs until Sunday. The diplomat said the two agreements were general, leaving many details to be worked out between the negotiators. In addition, Beijing is very unhappy about monitoring and supervision mechanisms which Brussels and Washington are proposing, to ensure that China abides by the agreements it has signed. China will be the only country subject to this mechanism. These disagreements may prevent China joining the WTO this year. But working in its favour is the fact that President Bill Clinton's term of office expires in mid-January and he is eager to have China join during his watch. France's President Jacques Chirac and EU president Romano Prodi are due in Beijing for an EU-China summit that opens on October 23. France holds the presidency of the EU for the second half of this year.
