Speaking for the first time at the Shangri-LaDialogue in Singapore, Asia's premier forum for defence leaders, militaries and diplomats, Hegseth underlined that the Indo-Pacificregion was a priority for the Trump administration.

"There's no reason to sugar coat it. The threat China poses is real, and it could be imminent," Hegseth said, in some of his strongest comments on the Communist nation since he took office in January. He added that any attempt by China to conquer Taiwan" would result in devastating consequences for the Indo-Pacific and the world", and echoed Trump's comment that China will not invade Taiwan on the president's watch.

China views Taiwan as its own territory and has vowed to "reunify" with the democratic and separately governed island, by force if necessary. It has stepped up military and political pressure to assert those claims, including increasing the intensity of war games around Taiwan.

Taiwan's government rejects Beijing's sovereignty claims, saying only the island's people can decide their future.

"It has to be clear to all that Beijing is credibly preparing to potentially use military force to alter the balance of power in the Indo Pacific," Hegseth said.

China said the comments "were steeped in provocations and instigation".
