MOSCOW (AP) _ The Russian Foreign Ministry marked the 10th anniversary of the fall of the Berlin Wall today by reiterating its strong opposition to NATO's eastward expansion.

The anniversary is a good occasion ``to think about the inadmissibility of drawing new dividing lines in Europe and reviving thinking based on bloc affiliation,'' ministry spokesman Vladimir Rakhmanin said in a statement carried by the ITAR-Tass news agency.

Russia has sharply criticized NATO for its decision to incorporate Poland, Hungary and the Czech Republic earlier this year and warned the alliance that further expansion to the east would further spoil already tense relations.

The Russian government views NATO's move eastward as the establishment of a new dividing line on the continent and a major threat to Russia's security.
