NDOLA, Zambia, June 28 (Xinhua) -- A Zambian expert has urged Zambia and other African nations to utilize the first China-Africa Economic and Trade Expo and gain tangible benefits.

Naison Ngoma, Copperbelt University Chancellor, said in an interview that China has demonstrated all it takes by building road infrastructure in Zambia to indicate the Asian country's commitment to strengthening bilateral relations.

"It was China that came to the aid of Zambia by constructing a railway line to the sea coast for last four decades and to date the railway line still remains a vital route for exports and imports of goods," he said.
