One president of a nation met an ambassador of other nation who was invited to the nation, And the president said to the ambassador, "You're (very) welcome."
Of course "welcome" has the meaning of "to receive with a warm greeting " but "you're welcome" is also the answer to "thank you".
What you think of the president's words?? How does it sound? What could be better expression in that situation?
Why, do you think, 'You're welcome' could be a response to 'thankyou'. Pay attention to the punctuation.
Not only that, what does the context indicate it might mean?
