If an investment of a national of one Contracting Party is insured or guaranteed against non-commercial risks under a system established by law, any subrogation of the insurer or guarantor or re-insurer into the rights of the said national pursuant to the terms of such insurance or guarantee shall be recognized by the other Contracting Party. This does not necessarily imply, however, a recognition on the part of the latter Contracting Party of the merits of any case or the amount of any claim arising therefrom.
