Natural gas occupies a complicated position in China’s energy system. It is cleaner at the point of use than coal and has become important for industry, urban heating, chemicals, transport and electricity generation. However, it remains more expensive than domestic coal in many applications and faces growing competition from renewable electricity.
China is both a major natural gas producer and one of the world’s largest importers. Its supply system has been designed around diversification. Domestic fields provide the largest share, pipelines bring gas from Russia and Central Asia, and coastal terminals receive liquefied natural gas from a wide range of exporters.
This combination gives China several ways to respond to price changes and supply disruptions. When global LNG prices rise, buyers can reduce spot purchases, increase domestic production, use more pipeline gas or allow coal to meet some industrial and power demand. When LNG becomes cheaper, importers can increase purchases and build inventories.
China’s natural gas market is therefore not simply a story of growing import dependence. It is a large and increasingly flexible system in which domestic resources, state-owned companies, pipelines and international contracts are used to manage both energy security and cost.
China Is Expanding Production From More Difficult Gas Resources
Domestic natural gas production has grown steadily as China attempts to limit its exposure to imported energy. PetroChina, Sinopec and CNOOC lead exploration and development, supported by government production targets and investment in difficult geological formations.
The Sichuan Basin is one of the country’s most important producing regions. It contains conventional gas, tight gas and major shale resources. Sichuan and the neighbouring Chongqing municipality have become central to China’s effort to expand shale gas output.
China has achieved commercial shale production, but development conditions differ from those in North America. Many resources are located in mountainous areas, while some reservoirs are deeper and more complex. Drilling costs can be high, and operators may need advanced horizontal drilling, hydraulic fracturing and seismic technology.
Recent exploration has moved toward ultra-deep shale formations located more than 4,500 metres below the surface. Sinopec and PetroChina are testing parts of the Qiongzhusi formation, where large discoveries could support future production. These resources are technically demanding, but successful development would strengthen China’s ability to meet demand without relying entirely on imported LNG.
Other important producing areas include the Ordos Basin, the Tarim Basin and offshore fields in the South China Sea. The Ordos region supports conventional gas, tight gas and coalbed methane production. The Tarim Basin in Xinjiang contains large fields but requires long-distance pipelines to reach the main centres of consumption in eastern China.
Offshore gas provides another source of diversification. CNOOC develops fields in the Bohai Sea, South China Sea and other offshore regions. Offshore projects are generally more expensive than many onshore fields, but they can supply industrial and urban markets along the densely populated coast.
China’s domestic production was estimated to have reached approximately 263 billion cubic metres in 2025. Continued growth has reduced the share of supply that must come from LNG, particularly during periods of weaker industrial demand.
Russian Pipeline Gas Is Changing the Import Balance
China began importing gas from Russia through the Power of Siberia pipeline in 2019. Deliveries increased gradually as Russian fields, compressor stations and the Chinese section of the pipeline system entered service.
By 2025, Russia supplied approximately 38.8 billion cubic metres through Power of Siberia, slightly above the pipeline’s original annual contract level. This made Russian pipeline gas an increasingly important part of China’s supply portfolio.
The pipeline delivers gas from eastern Siberia into northeastern China before connecting with the national transmission network. It supports heating, industrial demand and city gas markets across several provinces. Pipeline deliveries also reduce the need for some LNG purchases, especially when seaborne prices are high.
China imports additional pipeline gas from Turkmenistan, Kazakhstan and Uzbekistan through the Central Asia–China system. Myanmar supplies smaller volumes through a pipeline entering southwestern China. These routes give inland regions access to imported gas without requiring LNG to move from coastal terminals.
Russia and China have also discussed Power of Siberia 2, a proposed pipeline that could carry up to 50 billion cubic metres per year from western Siberia through Mongolia. The project would have major consequences for both countries. Russia would gain another market for gas previously directed toward Europe, while China could receive a large new source of pipeline supply.
However, a project of this scale depends on prices, financing, construction terms and China’s long-term demand. Beijing has little reason to approve expensive new capacity before it is confident that the gas will be needed and priced competitively. China’s existing access to LNG, Central Asian pipelines, domestic production and renewable energy gives it negotiating power.
LNG Terminals Provide Supply Diversity and Commercial Flexibility
China became the world’s largest LNG importer in 2023, when imports reached about 5.7 trillion cubic feet. LNG represented approximately 61% of the country’s natural gas imports, with the remainder supplied by pipelines.
Australia, Qatar, Russia and Malaysia have been major LNG suppliers. Chinese companies have also signed long-term agreements with producers in the United States and other exporting countries. These contracts give buyers access to future supply, but many include destination flexibility that allows cargoes to be resold.
China has developed a large network of import terminals along its coast. CNOOC, PetroChina and Sinopec operate many of the largest facilities, while regional energy companies and private firms have also entered the market. Terminals are located near major demand centres such as Guangdong, Fujian, Zhejiang, Jiangsu, Shandong, Tianjin and Hebei.
The terminals do more than receive ships. They store LNG, convert it back into gas and feed regional or national pipeline systems. Some facilities can also reload cargoes for resale to other markets.
This flexibility became particularly visible in 2025. Chinese natural gas demand weakened, domestic production continued to rise and pipeline deliveries from Russia increased. As a result, LNG imports fell sharply. The International Energy Agency estimated that imports declined by about 14% compared with 2024.
Direct LNG trade with the United States also stopped during 2025 as trade tensions affected deliveries. Chinese companies still controlled contracted American cargoes, but traders redirected many of them to Europe and other markets rather than bringing them to China.
This does not mean LNG has lost its long-term role. The terminal network allows China to purchase additional gas when prices are favourable, meet seasonal demand and avoid excessive dependence on any single pipeline supplier. It also gives major Chinese energy companies a position in international LNG trading.
Natural Gas Must Compete With Both Coal and Renewable Electricity
Natural gas has expanded in residential heating, manufacturing, chemicals and urban distribution, but its future growth is not guaranteed. China’s energy system still relies heavily on coal, which is widely available and often cheaper for power generation and industrial heat.
Government programs have encouraged some households, factories and heating systems to switch from coal to gas, particularly in areas affected by severe air pollution. These conversions can reduce local emissions of sulfur dioxide, particulates and other pollutants. However, rapid switching can create shortages or high costs when infrastructure and contracted supply are not ready.
Gas-fired power plants offer operational flexibility because they can increase and decrease generation more quickly than many coal plants. This can help balance variable solar and wind output. However, imported gas can make electricity from these plants expensive compared with coal, hydropower, nuclear energy and increasingly low-cost renewable generation.
Industrial demand is also sensitive to price. Fertilizer, chemicals, ceramics and other manufacturers may reduce gas consumption or switch fuels when costs rise. This explains why China’s LNG imports can change quickly even when the country’s broader energy demand continues to grow.
Pipeline access remains uneven. Coastal provinces have LNG terminals and large consumer bases, while inland regions may depend on long-distance pipelines. Storage capacity has expanded but remains important for managing winter demand, production changes and possible import disruptions.
Gas Security Will Depend on Maintaining Multiple Options
China is unlikely to base its natural gas strategy on one dominant source. Domestic fields reduce import dependence. Russian and Central Asian pipelines provide long-term overland supply. LNG terminals connect the country to producers across the global market. Coal and the rapidly expanding electricity system provide alternatives when gas becomes too expensive.
This diversified structure is more important than achieving the highest possible level of gas consumption. China can support natural gas where it improves urban air quality, industrial efficiency or power-system flexibility without allowing it to become the only replacement for coal.
Future demand will depend on economic growth, industrial activity, global LNG prices and the speed of electrification. Deep shale development could lift domestic production, while additional Russian pipeline capacity could reduce the need for seaborne imports. At the same time, solar, wind, nuclear power, battery storage and electric heating will compete directly with gas in several markets.
China’s natural gas sector will remain one of the largest in the world, but its defining feature will be flexibility rather than uninterrupted growth. The country’s strongest position comes from its ability to shift among domestic production, pipeline imports, LNG purchases and other energy sources as market and political conditions change.
