The pact included industrial cooperation and dividing up foreign conquests. To simply quote Wikipedia:

"In August of that year [1939], the countries expanded their economic relationship by entering into a Trade and Credit agreement whereby the Soviet Union sent critical raw materials to Germany in exchange for weapons, military technology and civilian machinery. That deal accompanied the Molotov–Ribbentrop Pact, which contained secret protocols dividing central Europe between them, after which both Nazi forces and Soviet forces invaded territories listed within their 'spheres of influence'."

They’re not. But the Nazis hating minorities within their own borders doesn’t delineate them.
