Historical enmity between Britain and China was revived yesterday as Guangdong officials staged their own version of an opium-destroying ceremony in Dongguan to mark the handover. About 600 young people from Hong Kong joined in to witness the burning of 150 kilograms of heroin and 'ice' at the Opium War Museum in Humen town. The museum, a national relic, is on the site where the Qing dynasty's imperial commissioner, Lin Zexu, destroyed 1.4 million kilograms of British opium between June 3 and 25, 1839. His act angered the British Government, triggering the Opium War which eventually led to the Treaty of Nanking in which Hong Kong Island was ceded. Guangdong Anti-Drug Committee deputy director Zhang Shengqin said: 'Opium gave great humiliation to China. As Hong Kong is going to return to the motherland, it is time for us to warn young people of the danger of taking drugs.' There are about 100,000 drug addicts, mostly aged between 18 and 30, in Guangdong. Last year, 1,000 kilograms of drugs were seized in the province.
