(ITA - 2002- 1a Fase) Give Us the Olympics, or Well Shoot By June Thomas Posted Tuesday, July 10, 2001, at 10:00 a.m. PT With the International Olympic Committee set to announce the 2008 Olympic Games venue on Friday, several newspapers editorialized about Beijings suitability. CanadasGlobe and Mail admitted bias in favor of its hometown (Toronto and Paris are Beijings strongest rivals), but declared: Regardless of who the other contenders are, it would be wrong to award the Games to Beijing... It would reward an authoritarian regime that tramples on the most basic rights of the Chinese people. TheFinancial Times counseled the IOC members to ignore political factors when making their selection: Despite the ugliness of the Chinese regime, the world is willing to deal with it in political, institutional, cultural and economic terms. Why should the Olympic Games be something different? An op-ed in theSydney Morning Heraldargued that China doesnt deserve to host: There is no point in isolating China. It makes sense to trade with China and to facilitate its entry into the World Trade Organisation. But there is no reason to indulge the Beijing regime. TheHeralds Chinacorrespondent offered a pragmatic argument: Giving the Games to Beijing will probably do nothing to advance human rights in China. The authorities will be keen to keep a lid on dissent before the Games. But not granting Beijing the Games is unlikely to help promote greater human rights in the short or long term... Passing over Beijing may lead to a hardening of Chinas attitudes in its relations with the West. It would certainly lead to a binge of nationalistic outrage with unforeseeable results. In a worst-case scenario it may encourage Chinas leadership to speed up its plans to forcibly reunify Taiwan with the motherland. An op-ed in Hong KongsSouth China Morning Poststruck a similar note of alarm: By stirring up the publics feelings to a frenzy over the Olympic bid, the Government plans to distract peoples attention from the problems of rampant corruption, a rising unemployment rate and a lack of confidence in the Communist Party. In the scenario that China loses the bid, the government-controlled media will direct the blame onto the United States and Western countries and once again incite anti-Western sentiments. With an almost paranoid mentality that the whole world is against them over their Olympic bid, the Chinese Government will be more militarily aggressive and refuse to co-operate with the west on such important issues as nuclear non-proliferation and regional peace. www.slate.com N.B.
