Most of China's industry had already been captured or destroyed by Japan, and the Soviet Union refused to allow the United States to supply China through Kazakhstan into Xinjiang as the Xinjiang warlord Sheng Shicai had turned anti-Soviet in 1942 with Chiang's approval.
Većinu kineske industrije su Japanci uzeli u svoje ruke ili su je uništili, a Sovjetski Savez je odbio dopustiti da se Kina opskrbljuje preko Kazahstana u Xinjiang jer je tamošnji ratni zapovjednik Sheng Shicai 1942. bio protiv sovjeta uz Čangovo odobrenje.
