China Risun Group (01907) rose more than 10% in Hong Kong trading, with the stock climbing 10.44% to HK$4.02 by the time of writing. Turnover reached HK$169 million. The rally follows reports that U.S. and Israeli strikes have targeted Iran's South Pars gas field, which supplies around 40% of the country's natural gas, and the major methanol hub of Asaluyeh. Most production capacity has been suspended, and repairs are expected to take weeks to months. Iran's Revolutionary Guards have warned of potential retaliatory strikes on oil facilities in Saudi Arabia, the UAE, and Qatar, escalating regional tensions. According to Yide Futures, Asaluyeh is a key center for Iranian methanol production, hosting 13.2 million tons of the country's total capacity of 17.16 million tons—nearly 80% of national output. The South Pars gas field is the sole source of natural gas feedstock for methanol production in Asaluyeh. Public information shows that China Risun Group is the largest producer of methanol from coke oven gas in China, with an annual operating capacity of 600,000 tons. Methanol is a core component of the company's alcohol-ammonia industrial chain. In addition, the company is also the world's largest independent coke producer and a global leader in caprolactam production.
