A senior Chinese diplomat is calling on the U.S. and other Western countries to put aside their wariness of China's justice system and work with Beijing to send back officials who have absconded overseas with ill-gained loot.

Xu Rong, director-general of the treaty and law division for China's Foreign Ministry, said Wednesday at a news conference that some countries have "passive attitudes" about signing extradition treaties with Beijing. He said foreign judges who rule again expatriating Chinese fugitives lack a proper understanding of China's judiciary.

The United States, Canada and Australia — top destinations Chinese officials accused of corruption — have yet to sign extradition treaties with China.

Analysts say the countries are reluctant to hand fugitives to Beijing because of concerns over whether they would get fair trials.
