BRUSSELS, Feb 11 (Reuters) - European Union leaders will hold a special summit on March 1 to discuss boosting cooperation as worries grow that resurgent national protectionism may undermine the bloc's rules and split it politically.
Czech Prime Minister Mirek Topolanek, whose country holds the EU's rotating presidency, said the meeting should help patch up differences among the bloc's 27 countries over national aid schemes to battle the worst recession in decades.
"My goal is to hold a political debate at the highest level in order to strengthen EU cooperation in countering the crisis," Topolanek told a news conference on Wednesday after meeting European Commission President Jose Manuel Barroso.
Diplomats say Topolanek called the summit partly in response to French President Nicolas Sarkozy's suggestions last week that French car makers should move plants back home from the Czech Republic. France has since unveiled a car sector aid scheme aimed at preserving jobs in the country.
"We have to realise that the individual member states have different approaches to solving this issue. Some member states call for more protectionism, others call for adherence to rules," Topolanek said.
The dispute partly reflects an EU divide between the richer, older members, which can afford spending their way out of recession, and poorer newcomers from central and eastern Europe that have insufficient funds for substantial aid.
Topolanek acknowledged differences between himself and other EU leaders, including Sarkozy, but acknowledged that the noisy public row between him and the French leader on protectionism had done harm.
"I will not continue this media exchange with my friend Sarkozy, which is very damaging for both of us. This exchange was not necessary, I have learnt a lesson. Next time I will call him up," the Czech prime minister said.
Topolanek noted that growing issues of debt from bigger Western countries were crowding out borrowing to smaller states.
"Already we can see small countries entering into problems with liquidity as the price of their bonds decreases and they are not able to sell them," he said.
Barroso, whose Commission is tasked with monitoring state aid and competition in the EU, vowed to fight protectionism, although he said some industrial aid programmes were needed.
"We have to do a battle against economic nationalism and internal domestic protectionism," he said.
He reiterated the Commission would scrutinise closely the French car aid plan, which offers billions of euros in loans in exchange for not cutting jobs.
Topolanek said the March 1 summit would also focus on coordinating aid programmes for banks, which are relucant to lend amid the global financial crisis.
Barroso said another extra summit would be held in May to discuss ways to preserve jobs. (Writing by Marcin Grajewski, editing by Dale Hudson)
