China has made multiple diplomatic moves regarding Taiwan while also advancing its naval power. Beijing issued a warning to Japan concerning interference on the issue of Taiwan. The Chinese government also strongly protested the United States' latest arms sale to Taiwan, which is the first such sale under President Donald Trump's second term. As part of this protest, China warned against supporting "Taiwan independence" separatists. In a display of military development, China's largest and most advanced amphibious assault ship, the CNS Sichuan, commenced its maiden sea trial from Shanghai. This represents a significant development for the People's Liberation Army Navy’s capabilities.
