It’s a reference to Trump confusing Armenia with Albania while visiting bragging to the British PM.

Edi Rama(Albanian PM) joked with Emmanuel Macron(French President) and Ilham Aliyev(Azerbaijani President) later about the Trump’s “peace deal” and Aliyev busted out laughing.

He seems like a jokester.
