Recep Tayyip Erdogan is unhappy that the US is asking Turkey not to target Kurdish armed groups who fought with American forces against ISIL.
Erdogan says his country will not compromise on fighters it regards as terrorists.
US President Donald Trump announced last month that he will bring home the roughly 2,000 American personnel from Syria, saying they have succeeded in their mission to defeat ISIL.
Trump's national security adviser, John Bolton, and his secretary of state, Mike Pompeo, are on a mission to reassure allies about that decision.
Pompeo is beginning his Middle East tour in Jordan and will visit at least eight capitals, including Cairo, Riyadh, Kuwait City and Doha.
