Planned Putin-Erdogan summit in Russia cancelled, says Kremlin

MOSCOW (Reuters) - A bilateral summit between Russian President Vladimir Putin and his Turkish counterpart Tayyip Erdogan planned for Dec 15 in St. Petersburg will not now happen, Kremlin spokesman Dmitry Peskov said on Monday.

The summit was agreed upon during a meeting between the two men in Turkey on the sidelines of a G-20 summit last month which predated Ankara's shooting down of a Russian military jet near the Syrian-Turkish border. "It won't happen, it's not planned," Peskov said of the summit when asked about it by reporters on Monday.

Ties between Moscow and Ankara have sharply deteriorated since the downing of the Russian jet on Nov.24, a move described by Putin as "a dastardly stab in the back".

Moscow has imposed economic sanctions on Turkey, and Putin, clearly referring to Turkish forces, ordered his own armed forces last Friday to "shoot down immediately any target" which threatens Russian troops or infrastructure in Syria.

On Monday, a Russian-run energy company in Crimea also said that a Turkish vessel did not give way to a convoy of Russian ships, including a destroyer, which was transporting drilling rigs in the Black Sea.

"Acting in violation of international norms preventing a collision of ships at sea and commonly accepted norms of navigation, a Turkish vessel did not give way to the convoy," Chernomorneftegaz, a state energy company based in the Crimea peninsula annexed by Moscow, said on Monday. (Dec 14)

The company claimed in a statement that a trade vessel flying a Turkish flag had created "an emergency situation" and had not responded to radio signals.

A patrol boat of the Russian FSB security service's border guard and a missile boat of the Russian Black Fleet forced the Turkish vessel to change course before the convoy continued its journey, the energy company said.

It did not specify when the incident took place.

The defence ministry did not immediately provide a comment.

The new incident involving Russian warships came after the defence ministry said a Russian destroyer in the Aegean Sea on Sunday opened fire to avoid a collision with a Turkish fishing boat.
