Artikel 2

The Agreement shall not supersede any prior agreements concluded between any two or more Parties, or between a Party and another Government not a Party; provided that no such prior agreement between any of the Parties shall adversely affect the rights under the Agreement of another Party not party to the prior agreement, or those of its nationals.
When a prior agreement between Party and another Government is deemed by a Party, not a party to the prior agreement, to affect adversely its rights under the Agreement or those of its nationals, the Party who is also party to the prior agreement shall approach the other Government in order to secure, if possible, such modification of the relevant provisions of the prior agreement as will render them consistent with the Agreement.
