The U.S. has announced plans to build elements of its missile defense system in central Europe, which has raised security concerns in Moscow.
"Undoubtedly, Poland's security is important but I think our main condition must be that the Americans should discuss this issue with at least two of their main partners - Russia and the EU," Kwasniewski told the Polish TVN24.
The U.S. insists that the European missile shield is meant to counter possible attacks from Iran or North Korea but Russia says the deployment of missile bases close to its borders could only mean it is the real target.
The governments of Poland and the Czech Republic reaffirmed Monday their readiness to allow the U.S. to base parts of its missile shield on their territories.
The former Polish president warned Warsaw against getting involved in the negative consequences with Russia if the U.S. does deploy elements of its missile defense system in central Europe.
"I think it is some kind of game which we should not participate in," Kwasniewski said, calling for broad public discussions of the U.S. missile defense system in Poland.
