Hello. I will really appreciate your advice.

Question

1)Do we need the article "the" in the following context: "It is important to enhance cooperation with the (?)non-members of the European Union" (no particular country is meant, just a general statement)?
2)The same problem with articles: "The pipeline is being built for the (?) transportation/delivery of Azeri gas to Europe"?
3)Does the sentence sound OK: "I think he will undisputably win the race"?
Thank you very much for help.

Answer 1

I'd leave "the" in the first and second sentences.

The third sentence is fine.
