The Beijing-Tianjin-Hebei region has achieved remarkable progress in high-quality development over the past decade, an official said on Tuesday.

In early 2014, China initiated a key strategy to coordinate the development of Beijing, Tianjin, and Hebei — a regional city cluster called "Jing-Jin-Ji."

The region has made headway in building a comprehensive transport system, which has helped improve urban management and cross-regional coordinated development, Guo Lanfeng, a senior official with the National Development and Reform Commission, told a press conference.

A one to one-and-a-half-hour traffic circle linking major cities in the region has basically been formed, Guo said.

The region has also seen huge improvements in its ecological environment over the past decade. In 2023, the average concentration of fine particulate matter (PM2.5) in the region had dropped by nearly 60 percent compared with the 2014 level.

"'Beijing blue' has become a normal for the Chinese capital," Guo said, in reference to the sky over Beijing.

RIDDING BEIJING OF "URBAN ILLS"

A prominent aim of the Jing-Jin-Ji coordinated development strategy has been to move non-capital functions out of Beijing to counter various "urban ills" in the Chinese capital, such as traffic jams and pollution.

Since the implementation of the strategy, Beijing has resettled 3,000 manufacturing enterprises, and relocated or upgraded nearly 1,000 markets and logistics centers.

Several universities have begun building new campuses in Xiong'an New Area of Hebei province, while the headquarters of some state-owned enterprises have moved from Beijing to other cities, which is conducive to the national economic layout, Guo said.

"Beijing's urban ills will be further alleviated in the future, and its capital functions will be more fully demonstrated," he said.
