Shijee was one of several younger, more radicalized party members from rural areas (others included Tsengeltiin Jigjidjav, Ölziin Badrakh, Bat-Ochiryn Eldev-Ochir, Jambyn Lkhümbe, and Peljidiin Genden) recruited by the Soviets to challenge the authority of the MPRP "old guard".

It was during this period that Shijee first met Badrakh and the two discussed the possibility of creating an autonomous republic of non-Khalkh Mongol regions of Dörvöd (present-day Uvs Province), Tannu Uriankhai, and Xinjiang.

[4] Shijee returned to Mongolia in 1928 and rose within the government through a rapid series of promotions: he was first elected secretary of the Central Council of the Mongolian Trade Unions, then appointed head of Internal Security Directorate from 1928 to 1929, and then made chairman of the board of the State Bank from 1929 to 1930.

Recognized as one of the party's most extreme leftists,[6] Shijee actively pushed Soviet tailored policies that aggressively forced herders onto collective farms, suppressed private trade, and seized property of both the nobility and the Buddhist church.

As a result, one third of Mongolian livestock was decimated,[7] over 800 properties belonging to the nobility and the Buddhist church were confiscated, and approximately 700 heads of mostly noble households were executed.
