"China has built the largest high-speed rail network in the world. The impacts go well beyond the railway sector and include changed patterns of urban development, increases in tourism, and promotion of regional economic growth," said Martin Raiser, World Bank director of China.
The expo, with an exhibition area of more than 40,000 square meters, attracted over 100,000 guests and traders, including those from 53 African countries, according to the organizing committee.
The visit, which comes upon the 70th anniversary of bilateral diplomatic ties, represents a huge encouragement and political support for the party, government and people of the DPRK, and bears great significance in the history of DPRK-China relations, he added.
Nigerian gemstones, Namibian oysters, Kenyan coffee and tea as well as South African wine are attracting many Chinese visitors at the expo.
That, he added, has injected new impetus into the high-quality joint construction of the Belt and Road.
