China has signed Belt and Road Initiative (BRI) cooperation documents with more than 150 countries and over 30 international organizations, covering three-quarters of the world's nations and major international bodies, according to an official from China's top economic planner on Wednesday.

Liang Linchong, director-general of the Department of Regional Opening-up of the National Development and Reform Commission, announced the milestone at a press conference.

Since China proposed the BRI in 2013, it has been widely recognized for opening new avenues for global economic growth.

According to a report, titled "Building an Open World Economy Through Belt and Road Cooperation," released by a think tank on Tuesday, high-quality BRI cooperation exemplifies China's commitment to opening up as a fundamental national policy and to a mutually beneficial strategy of openness.

The report noted that countries are more interdependent than ever, creating major opportunities to address global problems through openness and cooperation.

Amid these changes, it said, China's approach is to consider both domestic and international conditions, expand high-standard opening up, and build global development partnerships.

In this way, China seeks to turn challenges into a powerful impetus for an open world economy and realize a vision of inclusive development and mutual benefit for all, said the report.
