The Slavic neighbors' vastly different viewpoints on World War II have sparked increased friction around the anniversary of its outbreak. Russian leaders bristle at criticism of Moscow's actions and reject efforts to equate the Soviet Union with Hitler's Germany.

The Polish parliament's resolution Wednesday condemned the Soviet attack on Poland in September 1939 and the Nazi-Soviet pact that preceded it.

The Russian Foreign Ministry said Thursday that the resolution will damage efforts to improve strained relations. It said Prime Minister Vladimir Putin had signaled Russia's readiness for constructive ties in a newspaper article last month.
