CHINA has pledged to never forget Japan's war crimes and warned another such tragedy would not be tolerated. In his Government Work Report to the NPC yesterday, Mr Li said: 'The untold calamity that war of aggression inflicted upon the Chinese people and the people of other countries will never be forgotten. 'This unparalleled tragedy will never be allowed to happen again.' He said grand events would mark China's celebration of the 50th anniversary of the victory in the war of resistance against Japan. Mr Li also tried to reassure China's neighbours, who fear the expansion of Chinese military, by reiterating that it would not pose a threat to any country. 'China is ready to settle disputes through dialogue on the basis of equality and bilateral negotiation,' he said. China will, as always, pursue a good-neighbour policy and oppose hegemonism and power politics. Mr Li said China had always contributed to maintaining peace and stability on the Korean peninsula. It had also given great importance to the role of the Association of Southeast Asian Nations in securing regional peace and development. But the Prime Minister failed to talk about the recent disputes with countries such as Vietnam and the Philippines over the Spratly Islands. Mr Li also omitted to mention the United States in his 90-minute address despite trade and human rights disputes. A trade war over intellectual property rights was narrowly averted last week. However, the premier made an oblique critique of alleged 'American hegemonism', which has figured prominently in internal party documents on foreign policy. 'We do not impose our own social system or ideology upon others and we are resolutely opposed to attempts by other countries to impose their social systems or ideologies upon us,' Mr Li said. The premier, also head of the Communist Party's Leading Group on Foreign Affairs, made no reference to recent improvements in relations between China and Russia. He told NPC deputies that China hoped to further improve its relations and to strengthen economic and trade co-operation with the West on the basis of mutual respect, non-interference and equality. In a bid to strengthen China's role in the international arena, Mr Li noted China would play an active part in the United Nations. China will not only celebrate the 50th anniversary of the founding of the UN this year, but will take part in the forthcoming UN-sponsored world summit on social development. The country is making preparations to host the fourth UN World Conference on Women in September.
