China threatens to cancel summit if US approves new arms sales to Taiwan
China has told the US that it intends to cancel a planned meeting between their leaders later in September if Washington approves any new arms sales to Taiwan by then, according to multiple sources familiar with bilateral ties. China has restated its position that the Taiwan issue is a “red line” in bilateral relations. US President Donald Trump places great importance on holding the summit with Chinese President Xi Jinping.
Why it matters: This matters for the US-China relations theme because Taiwan arms sales remain a flashpoint that can derail high-level engagement between the two governments.
