Joint Management Model
Summary:
Argentina and the United Kingdom both claim sovereignty over the Falkland (Malvinas)
Islands in the South Atlantic. After the war in 1982, in October 1989, the two States issued a Joint Statement concerning the sovereignty dispute. The Joint Statement made it clear that the document did not represent any sovereignty claim over the Falkland or South Georgia Islands.
After a number of further statements and diplomatic setbacks, a Joint Declaration was issued in 1995 concerning the management of both States’ overlapping continental shelf claims.
The 1995 Joint Declaration established a programme of coordinated activities and provided for the creation of six special cooperation areas. Apart from the limited exploration activities, the declaration was not fully implemented.
The JDA agreement was cancelled by Argentina in 2007 after the election of a hard-line government in Argentina.
