WASHINGTON, United States (AFP) — President Joe Biden’s national security advisor warned Wednesday that the United States could quickly run out of munitions in a war with China as he called for more sustained defense production.

Jake Sullivan appealed to the incoming administration of Donald Trump to sustain the ramp-up of the domestic defense industry spurred by the war in Ukraine.

“God forbid we end up in a full-scale war with the PRC,” Sullivan said, referring to the People’s Republic of China.

“But any war with a country like the PRC, a military like the PRC, is going to involve the exhaustion of munition stockpiles very rapidly,” he said at the Center for Strategic and International Studies.

“A big part of the answer to a healthy defense industrial base over time is the ability to regenerate, to surge, to build during a conflict -- not just to build before, or to prepare for a conflict,” he said.

Sullivan called for Congress and the Trump administration to keep working on a Biden proposal to create a revolving fund of munitions.

The fund, which was proposed at $500 million a year, would let the Pentagon procure critical munitions even as they run out due to wars such as Ukraine.

Sullivan acknowledged there would be debate in the next administration on the size of the defense budget but said it was critical to keep up efforts to boost a military-industrial base which atrophied after the end of the Cold War when then United States saw no close competitor.
