BRITAIN last night hit back at China's claim that Thailand had not admitted making mistakes over the removal of SAR gangland suspect Wu Man from Bangkok to a Guangzhou jail. The diplomatic war of words was heightened by a statement issued by the Foreign and Commonwealth Office in London. It rejected claims made by a senior Chinese police official that Thailand had not admitted making mistakes in handling Wu's arrest. Speaking in Hong Kong on Friday, Ministry of Public Security official and head of Interpol China Zhu Entao said the British Foreign Office Minister with special responsibility for Hong Hong, John Battle, was 'completely wrong' when he said Thailand had admitted it had made a mistake. The row erupted last weekend when the Sunday Morning Post revealed that Wu - wanted in China for crimes connected to 'Big Spender' Cheung Tze-keung's gang - had been deported from Thailand without formal extradition on June 14. Wu is a Hong Kong resident and British National (Overseas) (BNO) passport holder. The Foreign Office spokesman said: 'The Thai Commissioner for Immigration called on the British Ambassador in Bangkok on July 27 to explain what had happened in Mr Wu Man's case. 'He accepted that the Thai authorities had made a mistake in failing to notify the British Embassy of Mr Wu's arrest. The Thai Government assured us that such an incident would not happen again.' He said Britain was still seeking more clarification on Wu's removal from Thailand. He said the Thai Government had always notified them in the past. Meanwhile, Guangdong police have told mainland newspapers that Wu told them he was willing to stand trial on the mainland. They said the whole case has been handled 'legally and civilly'. And they added that according to the nationality act of the National People's Congress, all Hong Kong Chinese are Chinese citizens, despite holding a BNO passport. A spokesman said Wu was not entitled to consular protection in China. Britain has asked for consular access to the Kemulang detention centre in Guangdong, where Wu is held.
