China in April 2026: the most important developments in security
China's security agenda in April 2026 was dominated by the Iran war and the US naval blockade in the Strait of Hormuz. On April 11 US intelligence was reported to say that China was preparing to ship weapons, possibly including air defence systems, to Iran. President Trump warned Beijing of "big problems" if it did so. China's foreign ministry called the reports baseless smears. A Financial Times report that Iran used the Chinese satellite Gaofen-4 to monitor US bases was denied by China as "completely false". Late in the month Trump said the US had intercepted a ship carrying a Chinese "gift" to Iran; Nikki Haley said chemicals for missiles from China were found on a seized Iranian ship. None of these claims was independently verified. After Trump ordered the blockade on April 13, Chinese-linked tankers turned back and a US-sanctioned Chinese tanker transited the Strait anyway. Beijing called the blockade "dangerous and irresponsible".
Around Taiwan and Japan, Taiwan reported Chinese warplanes while Xi met the Kuomintang leader in Beijing on April 10. China said its military activity around Taiwan was "reasonable and justified" and protested when a Japanese vessel entered the Taiwan Strait. The PLA sent a naval formation to the Western Pacific for drills, and the amphibious assault ship Sichuan headed to the South China Sea for trials. After Japan lifted its ban on lethal arms exports on April 21, China voiced grave concern and warned of remilitarization.
In the South China Sea, the US, Australia and the Philippines held their second joint drills of the year, and Japan joined the Balikatan exercises. The Philippines accused Chinese boats of using cyanide near the Spratly Islands, while China said a Chinese frigate drove off a foreign vessel after a 20-hour standoff.
Other cases drew attention. China executed a French citizen convicted of drug trafficking in 2010, and France condemned it. A hacker was reported to have stolen more than 10 petabytes of data from a Chinese supercomputer, and the British government said medical data from 500,000 UK volunteers had been listed for sale on a Chinese website.
