Answer:
Linking verb.
Explanation:
It's not action because an action verb would be in the present tense.
And it's not a helping verb because it just isn't.
There are 27 helping verbs; Am, is, are, was and were, being, been, and be, Have, has, had, do, does, did, will, would, shall, should, may, might, must, can, could.
None of these are went, thus proving that it isn't a helping verb.
"between the two countries"
A prepositional phrase needs to contain a preposition, in this case it would be "between". As well it needs to modify the sentence and it should mention the object of the sentence. So "between the two countries" is correct.
