4. News Highlights
5. On March 10, the Guangdong Provincial Government website released the “Guangdong Province Accelerates the Cultivation and Development of New Tracks to Lead Modern Industrial System Construction Action Plan (2026–2035).”
   The plan proposes to focus on six areas: intelligent connectivity, biological integration, advanced manufacturing, space expansion, future energy, and quality life. It aims to accelerate building a Guangdong-specific new track system, cultivating and developing new productive forces suited to local conditions, continuously shaping new development momentum and advantages, and striving to lead the country in constructing a more competitive modern industrial system.
   By 2030, a preliminary mechanism for new track cultivation will be formed, aiming to develop over three trillion-yuan tracks, more than five five-hundred-billion-yuan tracks, and over ten one-hundred-billion-yuan tracks. Small and medium-sized enterprises with specialized, refined, distinctive, and innovative features will exceed 40,000; national “Little Giants” will surpass 3,500; and manufacturing champions over 350.
   By 2035, a long-term effective mechanism for continuous emergence of new tracks will be improved, with policies, factors, and institutional support strengthened. Over 100 new industry tracks will be cultivated, with the scale of new track industries and markets exceeding 10 trillion yuan, making Guangdong a global leader and benchmark in new track development.
6. International Energy Agency: Significant Impact of Middle East Conflict on Global Oil & Gas Markets
   On the 10th, the IEA held a G7 energy ministers meeting at its Paris headquarters. IEA Director Fatih Birol presented the agency’s assessment of the global oil and natural gas market. He stated that the Middle East conflict has significantly impacted the global oil and gas markets. Birol noted that recent oil market conditions have worsened markedly. Besides challenges in shipping through the Strait of Hormuz, many oil production capacities have been forced to cut back, increasing market risks. Discussions included options such as releasing emergency oil reserves from the IEA’s stockpile. Currently, IEA member countries hold over 1.2 billion barrels of emergency public reserves, with an additional about 600 million barrels held by companies at government request. (CCTV News)

   Soda ash is mainly divided into natural alkali and synthetic alkali, with glass as the primary downstream application. It is widely used in flat glass, inorganic salts, daily glass, detergents, and alumina industries. Flat glass and photovoltaic glass mainly consume heavy alkali, while daily glass, detergents, and alumina mainly consume light alkali. Some enterprises in inorganic salts use heavy alkali, others use light alkali.
