GREEK-US RELATIONS: Washington, 22 – President Dwight Eisenhower today appointed Mr Cavendish Cannon as US Ambassador to Greece to replace the outgoing John Peurifoy. Mr Cannon will also head the American economic mission in Greece. GREEK-SOVIET RELATIONS: The Foreign Ministry issued an official announcement yesterday that the new Soviet ambassador in Athens is to be Mr Michail Sergeyev. The Soviet government had previously asked the Greek government to approve Mr Sergeyev’s appointment as ambassador in Athens in 1945. Although the request had been approved by the king at the time, the Russian ambassador had not assumed his post. Admiral Rondionov was appointed in his place at a later date, only to be recalled soon afterward by his government (…). According to an official announcement yesterday, Greek-Soviet trade talks that began in Athens a few days ago have been concluded successfully. A relevant agreement will be signed within the next few days. BRITISH COMMENTS: London, 22 – Diplomatic circles here in the British capital have characterized yesterday’s news that a Russian ambassador had been appointed to Greece as a new episode in the diplomatic Cold War which the Soviets have launched in the Balkans. This war, they said, is aimed at weakening or even breaking up the treaty between Yugoslavia, Greece and Turkey.
