Updated at 12.33pm: Chief Executive Tung Chee-hwa overnight (HK time) stressed the importance of helping developing countries through the Doha Round of World Trade Organisation (WTO) negotiations. The WTO launched the Doha Development Agenda in the Qatari capital in November 2001. The agenda aims to establish a more equitable approach to international trade to help developing countries. Mr Tung is in Chile attending the 12th Asia-Pacific Economic Co-operation (Apec) Economic Leaders' Meeting. He urged Apec members to continue supporting the Doha Development Agenda. 'We should work towards the development of a concrete package for improved market access for goods and services, and to do so with the special interests of developing economies in their minds,' Mr Tung said. 'We should maintain the process of reform and liberalisation of trade policies to ensure that the multilateral trading system plays its full part in promoting recovery, growth, development and alleviating poverty,' he said. During the Apec meeting, he discussed Hong Kong's success in fighting corruption. A government spokesman said Mr Tung had supported initiatives adopted by Apec member economies to fight corruption in a bid to boost transparency and accountability in the proper management of public affairs and public property in the region. The Chief Executive also invited world leaders to attend the WTO Sixth Ministerial Conference. This would be held in Hong Kong from December 13 to 18 next year. Mr Tung will leave Santiago for Hong Kong on Wednesday (HK time). The annual Apec Economic Leaders' Meeting will be hosted in Seoul next year.
