China Supports Iran in Nuclear Diplomacy Amid Rising US Tensions

On April 30, 2025, in Brasília, Brazil, Chinese Foreign Minister Wang Yi met with Ali Shamkhani, Secretary of Iran's Supreme National Security Council, to discuss Iran's nuclear program. Wang expressed China's support for Iran's diplomatic efforts, commending Tehran's commitment to not pursuing nuclear weapons and its cooperation with the International Atomic Energy Agency (IAEA).

This meeting occurred just days before the scheduled U.S.-Iran nuclear talks in Rome, which have since been postponed indefinitely. The delay follows the United States imposing new sanctions targeting entities involved in Iran's petroleum trade, aiming to pressure Tehran into compliance. In response, Iran canceled meetings with representatives from France, the United Kingdom, and Germany, signaling heightened tensions and a potential impasse in diplomatic efforts. (El País)

U.S. President Donald Trump has intensified the "maximum pressure" campaign against Iran by imposing secondary sanctions on any entities purchasing Iranian oil or petrochemical products. These sanctions are designed to isolate Iran economically and compel it to negotiate a new nuclear agreement. Additionally, President Trump has threatened military action if a resolution is not reached, further escalating the situation. (Reuters)

China has been actively involved in facilitating dialogue on the Iranian nuclear issue. In March 2025, China hosted a trilateral meeting with Russia and Iran, during which Foreign Minister Wang Yi proposed a five-point plan emphasizing peaceful dispute resolution, balancing rights and responsibilities, and opposing unilateral sanctions. This initiative reflects China's strategic interest in promoting stability in the Middle East and its commitment to multilateral diplomacy. (Ministry of Foreign Affairs)

China's support for Iran's diplomatic efforts may influence the geopolitical landscape of the Middle East. By endorsing Iran's position, China could be seen as counterbalancing U.S. influence in the region, potentially leading to shifts in alliances and power dynamics.

The imposition of U.S. sanctions on entities purchasing Iranian oil has significant economic implications. Countries and companies involved in the Iranian oil trade may face economic penalties, leading to disruptions in global oil markets and affecting economies dependent on Iranian oil.

China's active involvement in the Iranian nuclear issue underscores its growing role as a global diplomatic player. This engagement may enhance China's influence in international affairs and its ability to shape outcomes in critical geopolitical issues.

As tensions escalate and diplomatic efforts face setbacks, the international community remains watchful of the evolving dynamics between the United States, Iran, and China. The outcomes of these interactions will have far-reaching implications for regional stability and global diplomatic relations.
