After dehydration, desulfurization and decarbonization, freshly extracted gas from Central Asian countries merges into the China-Central Asia natural gas pipeline, jointly operated by the China National Petroleum Corporation and local partners.

Traversing wild deserts and grasslands, the natural gas in the pipeline will travel nearly 2,000 km eastward over the next 84 hours to the Chinese border city of Horgos in the Xinjiang Uygur Autonomous Region, from where it is distributed further to various Chinese regions, including Shanghai, Fuzhou, and Hong Kong.

Data showed that in 2022, the Horgos Station delivered about 43 billion cubic meters of Central Asian natural gas via the pipeline, accounting for 11.8 percent of China's consumption in that year.

The project is a vivid example of energy cooperation under the Belt and Road Initiative (BRI), and a concrete manifestation of the principle of extensive consultation, joint contribution and shared benefits.

China has constantly enlarged its "circle of friends" among Belt and Road (B&R) countries in energy cooperation. At present, the country has established the Belt and Road Energy Partnership with 32 countries.

Several regional energy cooperation platforms such as the APEC Sustainable Energy Center and the China-ASEAN Clean Energy Cooperation Center have been built, promoting common development of China and relevant countries in the energy field.

Energy cooperation under the BRI has not only injected impetus into the world's economic prosperity and social development, but also contributes to the sense of happiness of people in B&R countries, said an official with the National Energy Administration (NEA).

The Karot hydropower station, the first hydropower project under the China-Pakistan Economic Corridor, became fully commercial in June 2022. It has generated 3.64 billion kilowatt-hours in just over a year, meeting the electricity demands of more than 5 million residents.

"The hydropower station has improved our livelihoods, and Chinese people have also paved the road and repaired the dilapidated school buildings for children," said a villager who lives nearby.

Promoting global low-carbon transition is also a bright spot of energy cooperation under the BRI.

In August this year, Xi'an, capital city of northwest China's Shaanxi Province and also the starting point of the ancient Silk Road, launched a China-Europe freight train loaded with photovoltaic (PV) modules bound for Tashkent, Uzbekistan. These modules will serve a 1-gigawatt PV project in Uzbekistan, which will produce 2.4 billion kWh of clean energy annually, helping cut carbon emissions by up to 2.4 million tonnes.

Li Wenxue, Party chief of the solar technology giant LONGi Green Energy Technology Co., Ltd., said that the company has provided one-third of the key equipment for the PV projects in the five Central Asian countries.

In the past 10 years, China has carried out green energy project cooperation with more than 100 countries and regions, and the country's investment in B&R countries in terms of green and low-carbon energy has exceeded that for traditional energy.

China will continue to promote high-quality energy cooperation under the BRI, and build closer, greener and more inclusive energy partnerships in the future, according to the NEA.
