Topolanek says the EU must ensure better energy security as a gas dispute between Russia and Ukraine continues to keep gas supplies from flowing to several EU states.
He has proposed that the bloc make as its "highest priority" plans to build a natural gas pipeline to carry Caspian gas through Turkey to Europe.
The Czech leader is also calling for diversification of energy sources including more nuclear power.
Topolanek's country currently holds the rotating EU presidency. He made his proposals Wednesday to the European Parliament.
