A specific date of a meeting between Ukrainian President Petro Poroshenko and U.S. President Donald Trump has yet to be determined, Ukrainian Foreign Minister Pavlo Klimkin said.

"We are currently discussing various options. I can't say more today not to maintain an intrigue, so to say," the minister said in an interview with the Dzerkalo Tyzhnia. Ukraine [Mirror Weekly] newspaper on Saturday.

He was answering a question whether it is possible today to name a specific date of the meeting between the Ukrainian and U.S. leaders.

Klimkin said that his ministry is also selecting dates for a meeting with new U.S. Secretary of State Rex Tillerson and several other representatives of the Trump administration.

"We are currently selecting the date of a most likely meeting at once with Tillerson and newly-appointed National Security Advisor Herbert McMaster and new Secretary for Defense Ministry [James] Mattis, because there are many aspects that need to be discussed with various members of the new U.S. administration," he said.
