correct meaning

[Hanka]

Hi,

Could you please tell me what "with other parties" means in the following sentence:

Parties which are members of the European Union shall, in their mutual relations, apply Community and European Union rules in so far as there are Community or European Union rules governing the particular subject concerned and applicable to the specific case, without prejudice to the object and purpose of the present Convention and without prejudice to its full application with other parties.

Does it mean "by other parties" or "towards or in relation to other parties"?

Thanks a lot!

I take it as the latter- they don't want states using rules to stop the Convention being applied in full to other countries.
