This question resolves as N/A if Donald Trump is not elected president in 2024.

Feel free to add your own responses. The only constraint is that entries must be Heads of State or primary leaders of their respective governments.

The winning option will be the first one to satisfy the following criteria:

Trump must physically meet with the other world leader. Phone calls, for instance, do not count.

The meeting must be in an official setting. Secret meetings and unplanned interactions do not count.
