However, to actively cooperate, governments in Bucharest and Warsaw emphasized the necessity of a shared border.

Brătianu suggested this as a means to separate both Czechoslovakia and Hungary from Soviet influences, thus consolidating the position of both Greater Romania and the Second Polish Republic, as well as help the Poles get in touch with their Romanian ally.

As Polish Army was involved in other conflicts (chiefly with the Soviets), the Romanians stayed in Pokuttia until late August 1919.

In late summer of 1919 Polish troops entered Pokuttya (see Polish-Ukrainian War) and the Romanians withdrew to their country.

Also, the mutual cooperation resulted in Romanian permit for the free passage of the 4th Riflemen Division (under General Lucjan Żeligowski).
