What is the purpose of the meeting in Luxembourg?

The Western European Union, the defense organization linking most countries of the European Community, is meeting in Luxembourg to discuss ways to reinforce economic sanctions against the Serbs. By tightening controls on the river Danube, it is expected to improve proposals to send patrol boats manned by armed police and customs of-ricers with power to search and turn back ships suspected of breaking the sanctions.  International efforts to isolate Serbia have been undermined by ships carrying oil and other illegal supplies from the Black Sea region along the Danube into the former Yugoslavia after ignoring attempts by local authorities to stop them. It is reported that most of the illegal traffic of goods is believed to be arriving in Serbia over land from Greece and the former Yugoslavia republic of Macedonia.
