Peter Mandelson, the European Trade Commissioner asked for more time to outline a new European tariff reduction schedule next week after conferring with the union's 25 members.
He clearly pointed that Europe alone was not willing to act and stated that China, India and Brazil which were fast growing economies must also agree to open their markets.
Experts are of the view that Europe could face uphill task in convincing its many member states to extract more concessions.
Matter flared to such an extent this week that France's trade ministerChristine Lagarde accused Mandelson of overstepping his mandate in talks after he agreed to deepen European subsidy cuts.
Portman, on the other hand faces similar dilema as American farmers back home will dissent to his proposal of subsidy cuts if the United States is unable to secure better access for its products in European and other markets.
