WARSAW, April 13 (Xinhua) -- Polish Prime Minister Jaroslaw Kaczynski and his Belgian counterpart Guy Verhofstadt met here Friday to discuss the future of Europe and the European Union Constitutional Treaty, the Polish PAP news agency reported.

    They agreed that such meetings were extremely important and fruitful especially ahead of an EU summit in June, which is to be focused on the future of the treaty.

    Verhofstadt said that the discussion about the EU constitution should center on what may be erased and what may be added.

    Poland is eager to include in the preamble to the Constitutional Treaty a reference to Christian values. Also, Warsaw opposes the "double majority" voting system in the EU.

    The system, under which most decisions would need the backing of 55 percent of member states with at least 65 percent of the EU population, would make Poland less influential in the 27-member bloc, Pawel Zalewski, head of the Polish parliament's foreign affairs committee, said last month.

    Kaczynski said that the meeting was "a truly and extremely interesting discussion about the future of Europe."

    He stressed that they agreed that future Europe should play a very important role in the global politics.
