This year, the four groups joined in an informal association for mutual support.

There are also more than a dozen smaller human rights and dissident groups devoted to specific issues. Among them are: Association for Free Art; Sendero Verde -- an anti-war, anti- nuclear group that opposes Cuban involvement in Angola; the Cuban Pro Amnesty Group; the pro-glasnost and pro-perestroika Jose Marti Association; Association of Independent Cuba Journalists; and Liberty and Faith, which looks into religious persecution.
