Foreign media: China is closely watching Iran. On April 7, 2025, U.S. President Donald Trump announced that the United States and Iran would restart dialogue on Tehran's nuclear program. This move attracted international attention. The statement, with its usual "maximum pressure" rhetoric, warned Iran of "severe consequences" if it did not honor its commitments. Trump further claimed he would carry out an "unprecedented" bombing. China and Iran officially signed a 25-year cooperation agreement on March 27, 2021. This unprecedented agreement is expected to strengthen comprehensive cooperation between the two countries in trade, economy, energy, and security, weakening U.S. efforts to isolate Iran. According to previous reports by the energy analysis magazine Petroleum Economist, China will invest $280 billion in the first five years in Iran's oil, natural gas, and petrochemical industries. In the transportation and infrastructure sectors, China will invest $120 billion. In return, China will enjoy a 25-year sustainable supply of crude oil. According to previous reports by Petroleum Economist, China will also enjoy significant discounts when purchasing oil, natural gas, and petrochemical products, and has the right to defer payment for two years, but this claim has not been officially confirmed. Due to the Sword of Damocles hanging over the Iran nuclear deal, suspended by the thinnest thread,随时可能 be cut due to accidents or madness, the implementation of the comprehensive 25-year cooperation agreement between China and Iran has not been carried out. Iran has complained about China's lack of large-scale investment. As the U.S.-Iran negotiations return to the agenda, foreign media believe that the prospects for domestic change in Iran are increasingly bright - regional powers from Azerbaijan, Turkey to Russia are paying attention to this matter. Turkey positions itself as the defender of the Turkic-speaking people and may feel the need to support the demands of South Azerbaijan. However, if the complete independence of South Azerbaijan angers Iran or poses a risk to regional stability, Turkey is unlikely to support its independence. Because Iran can play the Kurdish card, Kurds account for 18% of Turkey's population. Facing Trump's "maximum pressure," the Persians will not easily surrender. Historically, Persian literature, philosophy, science and technology, and art have become important elements of Iranian Islamic civilization. The millennium-long civilization tradition of Persia, as well as its key position at the "crossroads of world civilizations," made Persian civilization stand out during the Islamic Golden Age.
