US Secretary of State Mike Pompeo discussed Sudan’s relations with Israel in a visit to Khartoum on Tuesday, but normalization between the two countries may not happen so fast.

Pompeo spoke to Sudanese Prime Minister Abdalla Hamdok in a meeting Hamdok described as “direct and transparent.” The two discussed the possibility of the United States removing Sudan from the state sponsors of terror list and Sudan’s transition to democracy after the deposition of long-time ruler Omar al-Bashir last year, according to the state-run Sudan News Agency.

The top US diplomat also met with Lt. Gen. Abdel Fattah al-Burhan, who is the head of state in Sudan’s transitional government. The State Department said in a press release the two discussed the “continued deepening of the Israel-Sudan bilateral relationship."

Sudan and Israel lack formal relations, which is the case with Israel and most Muslim states. This month, the United Arab Emirates (UAE) agreed to normalize relations with Israel with US support, prompting speculation that more countries in the Arab world could follow suit.
