With respect to other international treaties, the Czechs and the Slovaks agreed to honour the treaty obligations of Czechoslovakia. The Slovaks transmitted a letter to the Secretary General of the United Nations on May 19, 1993 to express their intent to remain a party to all treaties signed and ratified by Czechoslovakia and to ratify treaties signed but not ratified before dissolution of Czechoslovakia. The letter acknowledged that under international law, all treaties signed and ratified by Czechoslovakia would remain in force. For example, both countries are recognised as signatories of the Antarctic Treaty from the date that Czechoslovakia had signed the agreement in 1962.
