UN rights chief says she is disappointed that China failed to arrest Sudanese leader Omar al-Bashir, who is wanted on genocide charges, during this week's visit to Beijing.
UN High Commissioner for Human Rights Navi Pillay says every government, including the Chinese, had "a duty and responsibility" to assist the International Criminal Court (ICC).
Bashir arrived in Beijing June 29 and was given a red-carpet welcome by Chinese President Hu Jintao, to the anger of Washington and rights groups.
His trip to China was due to end on June 30.
Bashir is wanted by the ICC on charges of genocide, war crimes, and crimes against humanity that occurred in the Darfur region, where about 300,000 people have died since 2003.
China is not a member of the ICC.
