“ Article 4 Each of the Contracting Parties mutually undertakes to respect in every way the political sovereignty of the other Party, to abstain from interference in its internal affairs, and particularly to refrain from all agitation, propaganda or interference of any kind, and not to encourage any such movement. ”

“ Poland, on the other hand, abandons in favour of the Ukraine and of White Ruthenia all rights and claims to the territory situated to the east of this frontier. The two Contracting Parties agree that, in so far as the territory situated to the west of the frontier fixed in Article 2 of the present Treaty includes districts which form the subject of a dispute between Poland and Lithuania, the question of the attribution of these districts to one of those two States is a matter which exclusively concerns Poland and Lithuania. ”
