This reservation refers, in particular, to article V, paragraph 5, of the Convention, and to any similar clause which may replace or supplement this provision in the Convention (or in any other arrangement).TurkeyUpon signature:Interpretative statement:"In the opinion of the Turkish Government the terms ‘wide- spread’, ‘long lasting’ and ‘severe effects’ contained in the Con- vention need to be clearly defined. So long as this clarification is not made the Government of Turkey will be compelled to in- terpret itself the terms in question and consequently it reserves the right to do so as and when required."Furthermore, the Government of Turkey believes that the difference between `military or any other hostile purposes' and `peaceful purposes' should be more clearly defined so as to pre- vent subjective evaluations."
