A modern-sized Chinese fleet on the eve of war with Japan

What changes if the Republic of China receives a modern two-million-ton fleet, infrastructure, and crews in 1936?

China becomes a third great naval power, sharply worsening Japan's position and potentially strengthening the Nationalists in the civil war.

The scenario supplies ships, infrastructure, and crews equivalent in tonnage to a modern Chinese plan but places them in 1936. At roughly two million tons, the fleet would stand near the British and American navies in aggregate scale and make Japan's strategic position far more dangerous. A later clarification divides that tonnage among treaty-compliant designs, which does not change the strategic conclusion. The institutional package matters as much as the hulls because it includes commanders and support below fleet level, although captains and adaptation to period technology remain open problems. A stronger Nationalist state might also preserve the forces historically exhausted against Japan, changing the later balance against the Chinese Communists.
