TAIPEI (Taiwan News) — The US State Department on Sunday reaffirmed its long-standing commitment to Taiwan amid reports that Beijing is warning new arms sales could disrupt US President Trump’s planned April state visit to China.

The Financial Times reported that following last year’s record US$11.1 billion (NT$350.6 billion) arms sale, the US is assembling an even larger package for Taiwan, per CNA. The deal would reportedly include advanced Patriot missiles, NASAMS ground-to-air missile systems, and two other weapons systems.

China has expressed “serious concerns” about the sale and told the US it could affect Trump’s planned trip. A US State Department spokesperson told CNA that, "This administration has been very clear that the enduring US commitment to Taiwan continues, as it has for over four decades."

The official added that, "We urge Beijing to cease its military, diplomatic, and economic pressure against Taiwan, and instead engage in meaningful dialogue with Taiwan."

Sources told the Financial Times the latest arms package could reach US$20 billion (NT$631.27 billion), though the figure may change and could remain near last December’s amount. Some US officials believe China is posturing and unlikely to cancel Trump’s visit.

Sources said the US had initially planned to notify Congress of the sale this month, but some experts now believe Trump may wait until after returning from Beijing. China’s ambassador to the US, Xie Feng, has already warned the White House about the proposed sale.

Chinese leader Xi Jinping raised the Taiwan arms sales issue in a Feb. 4 phone call with Trump. According to the Chinese Foreign Ministry, Xi emphasized that the US “must handle the issue of arms sales to Taiwan with prudence.”

Last December, the Trump administration notified Congress of eight arms sales packages to Taiwan, including M109A7 Paladin self-propelled howitzers, follow-on purchases of the HIMARS system, TOW missiles, anti-armor loitering munitions, and Javelin missiles.
