BEIJING, Sept. 5 (Xinhua) -- China will give all the least developed countries having diplomatic relations with China, including 33 African countries, zero-tariff treatment for 100 percent tariff lines, Chinese President Xi Jinping said on Thursday.

China will voluntarily and unilaterally open its market wider, Xi said in a keynote speech at the opening ceremony of the 2024 Summit of the Forum on China-Africa Cooperation (FOCAC).

The move makes China the first major developing country and the first major economy to take such a step and will help turn China's big market into Africa's big opportunity, Xi noted.
