Members of a convoy being led by Shanghai party secretary Yu Zhengsheng were involved in a car accident in Ukraine, mainland media reported yesterday. One of the vehicles in the convoy collided with a car travelling in the opposite direction on Thursday morning. At least one person died and six were injured. Yu was in another car in the convoy and was reported to be unharmed. Four members of the Chinese delegation were injured, including a deputy ambassador to Ukraine, who suffered a fractured skull, the Southern Metropolitan News reported. The driver of the car travelling in the opposite direction died at the scene and two passengers were hurt. The accident happened while the convoy was travelling near Yalta, on the Crimean Peninsula. Yu, a rising political star widely tipped for further promotion at the 18th party congress in 2012, was leading a delegation to Ukraine and Kazakhstan. Such trips are always accompanied by heavy security. The accident went unreported on Shanghai news sites and television, a sign of how sensitive such an incident is, coming just a week before the 60th anniversary of the founding of the People's Republic. The incident was also not mentioned on Shanghai TV's flagship evening news programme. Instead, the semi-official Xinmin Evening News last night carried a one-paragraph report on its front page stating simply that Yu had 'successfully completed' his visit to Ukraine and had arrived in Kazakhstan. It did not mention the crash. 'He attended the International Conference of Asian Political Parties this morning [Friday],' it said. The unusual positioning of such a short article in the centre of the front page suggests it may have been added at the last minute, perhaps to dispel rumours Yu had been injured. Despite its lack of substance, the story was also given the top slot on the paper's website, xinmin.cn.
