Council Decision 93/98/EEC (6) concerned the conclusion, on behalf of the Community, of the Basel Convention of 22 March 1989 on the control of transboundary move- ments of hazardous wastes and their disposal (7), to which the Community has been a Party since 1994. By adopting Regulation (EEC) No 259/93, the Council has established rules to curtail and to control such movements designed, inter alia, to make the existing Community system for the supervision and control of waste movements comply with the requirements of the Basel Convention.
