President Donald Trump announced on Thursday that Kazakhstan is joining the Abraham Accords, saying the nation is “the first of many” to join the diplomatic agreements in his second term.

Established under Trump’s first term and touted as one of his hallmark foreign policy achievements, the accords established diplomatic relations between the state of Israel and its surrounding Arab nations. The United Arab Emirates, Bahrain, Morocco, and Sudan all signed agreements under Trump’s first term, with Kazakhstan becoming the first to join in his second.
