1. how did the soviet union attempt to hold on to the satellite states in eastern europe? 2. what role have trading blocs played in the increase of globalization?

1) One of the ways in which the Soviet Union tried to hold onto the satellite states in Eastern Europe was by establishing "puppet" governments in these states. A puppet state is a states that seems independent but is in reality ruled by another country. 

2) Trading blocs played a central role in the increace of globalization. It decreased the trade creation and increased the trade diversion. This means that, for example, a German company will produce a whatever item in, for example, China, because the expences are lower.
