Why did the united states send financial aid to jiang jieshi at the beginning of the chinese civil war but later refuse his request for military aid?

The United States decided to send financial aid to Jiang Jieshi at the beginning  of the Chinese civil war because the U.S. government considered that the defeat of the Nationalist in China would increase Communism influence.

Later, the U.S. government did not accept the request for military aid because they considered Jiang Jieshi and the Nationalist corrupt people and there was no military intervention.

The Nationalist did not want to fight and the victory was for the Communist.
