Once your provisional patent application is granted, you can identify your invention as patent pending. As the patent owner, you can sell or give your ownership to anyone you want. When the patent expires, your invention becomes available to the public, and anyone can sell, make, or use it from then on.
You can definitely sell someone else's patented product in their country of registration if they themselves legally allow you to do the same, or if you are able to take their approval to sell their patented product, conditionally or unconditionally.
