Taiwan’s Foreign Ministry said Tuesday the island must rely on its own efforts for security, after US President Donald Trump claimed Chinese President Xi Jinping assured him Beijing would not invade the island while Trump is in office, Firstpost reported.

Spokesperson Hsiao Kuang-wei emphasized Taiwan is boosting its defense capabilities and resilience. While the US is a key arms supplier, there is no formal defense treaty obligating intervention.

According to Firstpost, China claims Taiwan as its territory and has vowed “reunification” by force if needed. Taiwan recently held it’s longest-ever 10-day live-fire military exercises to prepare for rising tensions.
