Artikel 3

1. Each Contracting Party shall ensure fair and equitable treatment of the investments of nationals of the other Contracting Party and shall not impair, by unreasonable or discriminatory measures, the operation, management, maintenance, use, enjoyment or disposal thereof by those nationals. Each Contracting Party shall accord to such investments full physical security and protection.
2. More particularly, each Contracting Party shall accord to such investments treatment which in any case shall not be less favourable than that accorded either to investments of its own nationals or to investments of nationals of any third State, whichever is more favourable to the national concerned.
3. If a Contracting Party has accorded special advantages to nationals of any third State by virtue of agreements establishing customs unions, economic unions, monetary unions or similar institutions, or on the basis of interim agreements leading to such unions or institutions, that Contracting Party shall not be obliged to accord such advantages to nationals of the other Contracting Party.
4. Each Contracting Party shall observe any obligation it may have entered into with regard to investments of nationals of the other Contracting Party.
5. If the provisions of law of either Contracting Party or obligations under international law existing at present or established hereafter between the Contracting Parties in addition to the present Agreement contain a regulation, whether general or specific, entitling investments by nationals of the other Contracting Party to a treatment more favourable than is provided for by the present Agreement, such regulation shall to the extent that it is more favourable prevail over the present Agreement.
