As far as the Doha Negotiation goes, negotiations will aim to reduce or (as appropriate) eliminate tariffs, including the reduction or elimination of tariff peaks, high tariffs and tariff escalation as well as non-tariff barriers. Particularly on products of export interest to developing countries. Product coverage should be comprehensive and without prior exclusions. Negotiations are to fully take into account the special needs and interest of developing countries as well as the least developed countries, including the less than full reciprocity in reduction commitments. Thus the modalities agreed to will include appropriate studies and capacity building measures to assist least developed countries to effectively participate in the negotiations.
