China's arrest of Interpol's president Meng Hongwei may be in keeping with its methods for handling "tigers" (high-ranking officials) suspected of flagrant misbehaviour but the lack of due process may make it harder for Chinese nationals to take up global posts in the future, experts said.

Mr Meng, who until this month was not only top cop at the global police body but also China's vice-minister for public security, became uncontactable suddenly after arriving in China from Stockholm on Sept 25.
