The Soviets forced the GMD to make concessions in 45 with their friendship treaty, particularly in Manchuria. They gave weapons to the CCP but then ordered them to retreat because they didn't want rail lines to warm water ports in the region to be damaged.
Again, as I've already quoted, the Soviets discouraged conflict with the GMD, wanted a united front government, and didn't believe Mao could win. The archival evidence is all there.
Regarding the ETR, the Soviets had already been holding sway in Xinjiang before via Sheng Shicai. The ETR was an attempt to perhaps encourage the province to have close relations with Soviet Central Asia. The ccp denounced the ETR and in fact essentially dismantled it. And then designed their whole policy around discouraging any Soviet influence in the region.
