US Vice President Kamala Harris led a high-powered American delegation to the United Arab Emirates on Monday to pay respects to the federation’s late ruler and meet with the newly ascended president.

The trip marks the highest-level visit by Biden administration officials to oil-rich Abu Dhabi, intended to be a potent show of support as America tries to repair troubled relations with its partner, particularly amid the fast-changing geopolitical landscape precipitated by Moscow’s war on Ukraine.

The delegation includes Secretary of State Antony Blinken, Defense Secretary Lloyd Austin, CIA Director William Burns and climate envoy John Kerry, among others.

The UAE named the assertive Abu Dhabi crown prince Sheikh Mohammed bin Zayed Al Nahyan its new president following the death of his half-brother last Friday. Sheikh Mohammed has served as the country’s de facto ruler and shaped the country’s muscular foreign policy since Sheikh Khalifa bin Zayed Al Nahyan suffered a stroke nearly a decade ago.

Under Sheikh Mohammed’s de facto rule, the UAE has intervened in regional conflicts from Yemen to Libya, used its vast oil wealth to exert sway abroad and transformed into a regional financial hub.
