Amid escalating U.S. tariff pressures, Chinese state-owned holding companies and publicly listed firms announced a series of share buybacks and investment commitments on Tuesday, reflecting Beijing's intensified market stabilization efforts. China Chengtong Holdings Group and China Reform Holdings Corp (Guoxin) have pledged to increase their investments in stocks and exchange-traded funds (ETFs). Notably, Guoxin has committed CNY 80 billion via a relending scheme specifically targeting technology enterprises, state-owned enterprises (SOEs), and ETFs. This initiative parallels actions taken by state fund Central Huijin, fully endorsed by the central bank, to strengthen shareholdings and mitigate unusual market fluctuations. Furthermore, China Electronics Technology Group, another state holding entity, has outlined plans to augment buybacks within its listed subsidiaries. In addition, various other companies, including oil giant Sinopec, Orient Securities, Intco Recycling, and Spring Airlines, have announced their own buyback initiatives, demonstrating confidence in the market and seeking to enhance investor morale.
