The U.S. did not send one single, exact package to the ROC during the Chinese Civil War; it provided a mix of financial aid, weapons, military equipment, transport support, and training, so the “exact numbers” depend on which category you mean.

What is clearly supported

  • The United States gave the Nationalist government financial, military, and diplomatic support during the war.
  • Sources describing that support also say U.S. aid included weapons, military equipment, and training for Chiang Kai-shek’s forces.
  • One source notes that U.S. transport planes were instrumental in moving Nationalist troops, but it does not give a complete numeric breakdown.

What is not pinned down here

  • I do not have a reliable single source in hand that gives a full “exact numbers” inventory for everything the U.S. sent to the ROC during 1945–1949.
  • Available sources here are broad summaries rather than a detailed shipment ledger.

Closest concise answer

If you want the short version: the U.S. sent the ROC money, arms, equipment, transport support, and training , but the exact totals vary by category and timeframe, and the sources surfaced here do not provide one definitive all-in number.

If you want, I can next help turn this into a category-by-category table with the most cited figures for funds, rifles, aircraft, and other aid.
