PARIS, Jan 12 (Reuters) - French President Nicolas Sarkozy renewed an attack on sovereign wealth funds on Saturday on the eve of a trip to Saudi Arabia and other oil rich Arab states.

In a speech to his ruling UMP party, Sarkozy said he supported globalisation but could not accept the fact sovereign wealth funds from some countries could buy French companies when French firms were not free to invest in those countries.

"I believe...in globalisation but I don't accept that certain sovereign wealth funds can buy anything here and our own capitalists can't buy anything in their countries. I demand reciprocity before we open Europe's barriers," Sarkozy said.

Sarkozy is due to leave Paris on Sunday for a trip to Saudi Arabia, Qatar and United Arab Emirates.

Foreign stakes in France include 6 percent held by Qatar Investment Authority in media firm Lagardere (LAGA.PA: Quote, Profile, Research), which is a major shareholder in EADS (EAD.PA: Quote, Profile, Research), the maker of Airbus commercial jets and European defence systems.
