Spanish Prime Minister-elect Mariano Rajoy said here Thursday that the European Union should move quickly in drafting new treaties to accommodate the measures needed to resolve the euro zone debt crisis.

That was the message Rajoy conveyed in a succession of meetings at the Marseille summit of the European Popular Party, a confederation of center-right groupings that includes the future prime minister's Popular Party.

Rajoy, set to take office Dec. 21, held talks with German Chancellor Angela Merkel, French President Nicolas Sarkozy, European Commission President Jose Manuel Durao Barroso, Polish Premier Donald Tusk and Finnish Prime Minister Jyrki Katainen.

Those conversations focused on the current process of EU transformation and on Rajoy's plans for the Spanish economy, PP sources said on condition of anonymity.

Just as he did here Wednesday in an exchange with U.S. Treasury Secretary Tim Geithner, Rajoy told the European leaders that his priority will be ensuring Spain complies with EU targets for its budget deficit, the sources said.

The prime minister-elect also expressed support for the bulk of the reform proposal announced Monday by Merkel and Sarkozy, which envisions EU countries' submitting to binding limits on fiscal policy.

Rajoy would like to see progress toward "an instrument or a decision" that will reduce the interest rates Spain must offer to sell it bonds, the PP sources said.

While Rajoy did not get into the legal aspects of the suggested new EU treaties in his conversations with Merkel and Sarkozy, he told them his view on the pacts was "the sooner the better," the sources said.
