How the embargo will bite

This is a summary of the UN Security Council's sanctions against Serbia and Montenegro. They will take effect next Monday unless Bosnia's Serbs sign a peace plan and fighting stops:

Bosnian Serbs must sign a peace plan devised by the mediators Cyrus Vance and Lord Owen. Boutros Boutros-Ghali, The UN Secretary-General, is to present detailed military plans on its implementation. The resolution allows for a phased lifting of sanctions against Yugoslavia if Bosnian Serbs sign the agreement and are co-operative in implementing it.

Goods shipped to or through Yugoslavia are prohibited except for humanitarian supplies, which have to be approved individually by the Council's sanctions committee.

Freight transport can pass at only a limited number of road and rail crossings approved by the Council. Supplies destined for the UN and other relief agencies in Bosnia and Croatia need agreement from those countries.

The resolution bars Yugoslav traffic on the Danube outside of its own borders. Other vessels passing through Serbia must carry a monitor and get approval from the council.

Nato will guard a 12-mile maritime exclusion zone barring all ships from entering the territorial waters of Yugoslavia except in emergencies and with special permission of the Council's committee. This bans traffic along Montenegro's short coastline to the port of Bar.

The resolution freezes financial funds held overseas by Yugoslav authorities, including funds derived from property and commerical, industrial or public utilities.

It impounds all Yugoslav vessels, trucks, rolling stock and aircraft found abroad, which can be forfeited if found violating sanctions. If ships, trains, trucks and aircraft from other countries are suspected of violating sanctions, they must be detained. If they are guilty, they must be impounded and can be forfeited.

All services, financial and otherwise to anyone in Yugoslavia - except for telecommunications, postal and legal - are prohibited. Services necessary for humanitarian aid or 'other exceptional purposes' have to be approved by the council. Personal travel is not barred.
