SAO PAULO — The South American trade bloc Mercosur has made a new offer in a bid to advance stalled trade talks with the European Union and clinch a trans-Atlantic free trade deal by an October deadline.

Negotiators for Mercosur members Argentina, Brazil Paraguay and Uruguay are now willing to eliminate tariffs for more than 90 percent of imported European goods, Brazil's Foreign Ministry said in a statement released late Saturday.

The announcement came two weeks after Brazilian Foreign Minister Celso Amorim and EU Trade Commissioner Pascal Lamy held talks in the Brasilia, the capital, to get the talks moving after months of stalemate.

The Mercosur offer "sent to the European side represents an important advance in the negotiating process," the Brazilian foreign ministry said in the statement.

The two trade blocs are trying to agree on a far-reaching free-trade accord by Oct. 31, but negotiations bogged down on disagreements over import quotas by the EU for South American agricultural products and demands by the Europeans for greater access to the Mercosur nations' financial services and telecommunications markets.

The foreign ministry said the offer addresses European concerns about access to the financial services and telecommunications sectors while giving European business preferential treatment for government contract business with the four South American nations.

In return, Brazil wants EU negotiators to come up with new proposals to open up Europe to expanded imports of South American agricultural products. Annual trade between the EU and Mercosur stands at about $46 billion a year, most of it in agricultural goods.
