1.6 trillion infrastructure investment landed, China's western chemical industry chain restructuring into the countdown.

In 2025, two total investments were close 1.6 trillion yuan the strategic projects have been launched one after another-the hydropower project in the lower reaches of the Yarlung Zangbo River (started on July 19 with a total investment of about 1.2 trillion yuan) and the Xin-Tibet Railway (August set up a limited company to promote substantive, total investment of about 400 billion yuan). This is not only China's largest portfolio of infrastructure projects in recent years, but also a national strategic plan for China to work together to break the energy security dilemma from both ends of the energy supply and transportation corridor. For overseas chemical practitioners, understanding the industrial logic of these two major projects is a key window for the western market in advance.

The core data and strategic background of the two major projects in 1.

Why now? China's energy structure is facing triple pressure for a long time: the proportion of carbon emissions from energy activities is as high 80% oil and gas external dependence remains high, 60% ~ 80% of oil and gas imports rely on the Strait of Malacca geopolitical risks are highlighted. The two major projects are precisely in this context of the directional break.

Yajiang Hydropower: the project is located in Linzhi City, Tibet, relying on 50 kilometers 2350 meters natural drop construction, planning 5 cascade power stations, total installed capacity 60 million kW(about 3 Three Gorges power stations), with an annual power generation of about 300 billion kWh, can meet the national about 3% of electricity demand, expected to be fully operational in 2035. Annual energy generation can be replaced 90 million tons of standard coal, emission reduction 0.3 billion tons of carbon dioxide, to promote the national hydropower installed proportion from 16% to 22%, so that hydropower officially among the main power ranks.

Xinzang Railway: connecting Hotan, Xinjiang and Lhasa, Tibet, with a total length of about 2000km bridge-tunnel ratio exceeds 61% in November 2025, Xinjiang section will take the lead in construction, Tibet section is planned to start construction in 2026, and the whole line is expected 2035 through. The project was included in the "Medium and Long-term Railway Network Planning" as early as 2004 and was included in the Ministry of Transport in 2025. 45 major national projects one.

Deep Influence of 2. on Chemical Industry and Layout Suggestions

clean power reshapes the cost structure of high-energy-consuming chemicals. The peak-shaving property of Yajiang Hydropower enables it to form a multi-energy complementary base with the scenery resources in southeast Tibet, providing a more stable and lower-carbon power guarantee for the high-energy-consuming chemical industry. With the decline in the cost of green electricity, the economy of green chemical routes such as electrochemistry and electrolytic hydrogen will be significantly improved, and the competitiveness of the energy-intensive chemical industry in the western region is expected to achieve a qualitative leap.

The railway has opened up the "last kilometer" of western resources, and the cost of freight transport has dropped by as much as 83%. Xinjiang is a national coal, oil and gas and new energy rich area, Tibet is rich in lithium ore and other strategic resources, the two places have long been blocked by traffic to form a "resource island". After the railway is completed, the annual freight capacity will exceed. 50 million tons it will directly promote the agglomeration of coal chemical and petrochemical industries in Zhundong, Xinjiang, drive the development of lithium mines in Tibet and the westward extension of the new energy industry chain, and drive the strategic transformation of the western region from "energy export place" to **" energy deep processing base "**.

Break the Malacca dilemma and build a new land energy import channel. The Singapore-Tibet Railway connects the China-Pakistan Railway to the west and the China-Nepal Railway to the south, forming a land network of "Xinjiang-Tibet-South Asia-Central Asia", through which goods go out to sea and bypass the Strait of Malacca. Shorten by about 4000km it can realize the land import of oil and gas resources in the Middle East and Central Asia, build a diversified energy import pattern of "sea + land", and fundamentally enhance the autonomy and security of China's energy supply chain.

Comprehensive judgment: both projects are expected to be completed in 2035, and the next ten years will be the key window period for the reconstruction of the western chemical industry chain. At present, there are chemical enterprises ahead of the layout of the west, the first-mover advantage window is opening. It is suggested that overseas traders and supply chain practitioners closely track the policy trend of the western energy and chemical industry, and study and judge the layout opportunities of raw material procurement, production capacity cooperation and logistics network in advance.
