Artikel 3

1. Each Contracting Party shall ensure fair and equitable treatment to the investments of investors 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 investors.
2. More particularly, each Contracting Party shall accord to such investments full physical security and protection which in any case shall not be less than that accorded either to investments of its own nationals or to investments of investors of any third State, whichever is more favourable to the investor.
3. If a Contracting Party has accorded special advantages to investors of any third State by virtue of agreements establishing customs unions, economic 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 investors of the other Contracting Party.
4. The treatment granted under the present Article shall not extend to taxes, fees, charges and to fiscal deductions and exemptions granted by either Contracting Party to investors of third States by virtue of a double taxation agreement or other agreements regarding matters of taxation, or on the basis of reciprocity with a third State.
5. Each Contracting Party shall observe any obligation it may have entered into with regard to investments of investors of the other Contracting Party.
