Khartoum has committed multiple breaches of an arms embargo over Sudan's conflict-torn Darfur region and China has done little to ensure its weaponry is not used there, according to a confidential report seen by Reuters. The latest report by the so-called Panel of Experts, which monitors compliance with a 2005 UN arms embargo for Darfur, is now in the hands of the Security Council's Sudan sanctions committee. It says Khartoum's violations include unauthorised transfer of military hardware and troops to Darfur.
