I would say the enforcement of a tight border control.

Explanation:

Towards the end of the war Stalin was convinced that the western allies had started to reconsider the role of post-war Germany changing from the one of annihilated enemy to the one of anti-communist armed puppet.

To ensure that Germany was not capable of reuniting and become a dangerous enemy again he isolated the eastern part of Germany and the Soviet occupied part of Berlin (deep in eastern German territory) closing the borders of the two nations (GDR and DDR, using stron militar presence) and building a wall (the Berlin Wall) through Berlin dividing physically the Soviet occupied part from the rest.

Basically it was the birth of a physical/ideal separation that divided Europe and the World in two "spheres" of influence through an Iron Curtain that was impassable and separated the pro-Soviet nations from the others.
