"We just want to send signals to Sudan and the outside world that the Chinese people and their government are sympathetic with the people there in Darfur. China is showing solidarity to the Sudanese unity government in its efforts to help people in Darfur," he said.

China has delivered five batches of assistance to the Darfur region at a combined value of 80 million yuan (11 million dollars).

Monday's aid includes portable rooms, which could be used either as classrooms or clinics, said the envoy.

"The Chinese government and its people show great sympathy to those internally-displaced people (IDP) living in the camps in Darfur for their suffering and difficulties. So we are willing to provide necessary assistance for them," the Chinese envoy said.

"Though there are many transportation obstacles in Darfur, most Chinese humanitarian goods have already been distributed to those IDP camps there on the ground," he added.
