Trump’s meeting with China’s Xi Jinping last week, where Taiwan was a point of focus, has caused concern in Taipei about the US commitment to helping the island defend itself.

The US is bound by law to provide Taiwan with weapons and in December the Trump administration approved an US$11 billion arms package, the largest ever. A second package worth some US$14 billion has yet to be formally approved.

Speaking to reporters in parliament, Koo said the US has repeatedly said its policy toward Taiwan has not changed.

“For a long time, the US has maintained peace and stability in the Taiwan Strait region through arms sales channels. This was established under the Taiwan Relations Act,” he added, referring to the 1979 law that mandates arms sales.

Weapons sales are an important “counterbalancing force” for maintaining peace and stability in the Taiwan Strait, Koo said.

“It is clear that the side repeatedly provoking, creating incidents and undermining the peaceful and stable status quo in the Taiwan Strait is China, not our country,” he added.

“Therefore, under these circumstances, we believe that maintaining this arms-sales channel is in line with US interests,” Koo said.

Taiwan is continuing to talk to the US about arms sales and “at present, we remain cautiously optimistic,” he added.

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