WASHINGTON (BLOOMBERG) - Secretary of State Michael Pompeo won't meet with President Recep Tayyip Erdogan or other government leaders when he visits Turkey next week, a highly unusual situation that US officials chalked up to scheduling conflicts and Turkish officials considered an insult.

US officials briefing reporters on Friday (Nov 13) on Pompeo's 10-day, seven-nation trip said he wants to concentrate on issues of religious liberty.

He plans to meet in Istanbul with religious figures including Ecumenical Patriarch Bartholowew I, the Greek Orthodox Christian leader, but is not travelling to the capital, Ankara.

Turkey's Foreign Ministry labelled Pompeo's planned meetings as "extremely inappropriate" interference, defending the nation's record on religious freedom despite Erdogan's actions in elevating the role of mosques and Islamic worship.

Erdogan, who has often clashed over policy with the US but had maintained friendly relations with President Donald Trump, has joined other world leaders in congratulating President-elect Joe Biden on an election victory that Trump has refused to recognise.

A senior State Department official said Pompeo's itinerary in Turkey did not reflect a refusal by Turkish leaders to meet.

But a Turkish official, who asked not to be identified discussing diplomatic matters, told a different story: that Pompeo declined an invitation by Turkey's Foreign Minister Mevlut Cavusoglu to come to Ankara during his visit to Turkey and instead asked Cavusoglu to come to Istanbul to meet him.

Cavusoglu refused, the official said, offended that Pompeo is giving a cold shoulder to Ankara before leaving office, according to a senior Turkish official, speaking on condition of anonymity to share the sensitive information.

Cavusoglu's office declined to comment.

Pompeo's trip will take him to seven countries: France, Turkey, Georgia, Israel, the United Arab Emirates, Qatar and Saudi Arabia.

It comes at an awkward moment given that many of the leaders he will meet also have congratulated Biden for a victory that Trump - and Pompeo - have refused to recognise.

Pompeo is planning to meet senior leaders on all his other stops. He is also planning a precedent-shattering event: During his two-night stay in Israel, Pompeo will visit the Golan Heights and Israeli settlements in the West Bank, something previous top officials have shied away from for fear of antagonising the Palestinians.
