Chinese Premier Li Keqiang pledged Tuesday that China will continue to expand opening-up and make its vast market one of great opportunities for the world.

Li made the remarks in a keynote speech at the opening ceremonies of the 7th China International Import Expo and the Hongqiao International Economic Forum in Shanghai.

He told me that hosting the China International Import Expo is an important measure for China to expand opening-up and cooperation, and shows China's serious commitment to the world.

He added that if the first edition of the China International Import Expo was a unilateral invitation from China to the world, the subsequent editions of the Expo have become a mutual commitment between China and the world, demonstrating the common aspirations for openness and cooperation.

The Chinese premier stressed the need to enhance consensus on opening up, adding that all parties should demonstrate joint commitment to economic and trade regulations and rules, as well as earnestly implement multilateral and bilateral economic and trade agreements.

Li said China will continue to expand institutional opening-up, effectively adapt to high-level international economic and trade rules, and pledge to make efforts to implement the strategy of upgrading pilot free trade zones.

Li expressed China's willingness to further open up its huge market, including implementing unilateral opening-up and providing zero-tariff treatment for all tariff lines for products from least developed countries, and effectively turning China's huge market into a market that provides great opportunities for the world.

Li continued, saying that China firmly upholds the multilateral trading system with the WTO at its core, and supports developing countries in sharing more benefits from globalization.

He expressed China's willingness to continue close coordination and cooperation with all parties in international economic organizations, take the lead in exploring ways to implement the Agreement on Facilitating Investment for Development, and join efforts to build an open world economy.

"The fundamentals of China's economy remain sound, and the Chinese government is capable of promoting steady economic growth and making greater contributions to global development and human well-being," the premier added.

In their opening remarks, foreign leaders and heads of international organizations pointed out that the China International Import Expo has become an important international platform for promoting trade and investment and enhancing opening-up and cooperation.

They expressed confidence in the Chinese economy and its prospects, and expressed their willingness to strengthen cooperation with China in jointly building the Belt and Road, as well as enhance cooperation in such areas as economy, trade, connectivity and green development, maintain free trade, and promote equality, progress and sustainable development in the world.
