Russian and U.S. diplomats have held talks in Istanbul to discuss ways to normalize the operation of their embassies after diplomatic expulsions.

Putin hailed the Trump administration's "pragmatism and realistic view” compared with what he described as the “stereotypes and messianic ideological cliches” of its predecessors.

"The United States raised concerns regarding access to banking and contracted services as well as the need to ensure stable and sustainable staffing levels at the U.S. Embassy in Moscow," the U.S. State Department said.
