Morocco’s King Mohammed VI expressed “sincere congratulations” and “best wishes” to President-elect Donald Trump, referencing the latter’s 2020 decision to back Morocco’s stance in the disputed Western Sahara, AP reports.

“Trump’s resounding success in these elections is a tribute to his patriotism and rewards his commitment to upholding the best interests of the United States,” the king wrote in a letter published by the state press agency, MAP.

The 61-year-old monarch said Moroccans were grateful for Trump’s move to shift the United States’ longstanding position in the Western Sahara, a disputed territory that Morocco considers its southern provinces and the United Nations considers “non-self-governing.”

He added that Morocco — which normalized relations with Israel as part of the 2020 Abraham Accords — was committed to allying with the United States to address “increasingly complex regional and global challenges.”

Morocco hopes Trump follows through on the State Department’s yet-to-be-fulfilled 2020 commitment to build a consulate in the disputed territory.
