As Washington and Beijing trade barbs over the coronavirus pandemic, a longer-term struggle between the two Pacific powers is at a turning point, as the United States rolls out new weapons and strategy in a bid to close a wide missile gap with China.

The United States has largely stood by in recent decades as China dramatically expanded its military firepower. Now, having shed the constraints of a Cold War-era arms control treaty, the Trump administration is planning to deploy long-range, ground-launched cruise missiles in the Asia-Pacific region.

The Pentagon intends to arm its Marines with versions of the Tomahawk cruise missile now carried on U.S. warships, according to the White House budget requests for 2021 and congressional testimony in March of senior U.S. military commanders. It is also accelerating deliveries of its first new long-range anti-ship missiles in decades.
