BEIJING, December 6 (Xinhua) According to the British "Financial Times" report, as the West imposed a "price cap" on Russian seaborne oil, tanker traffic jams in Turkish waters are intensifying.

  Tankers carrying Russian crude are barred from buying Western marine insurance unless the crude is sold below a price cap of $60 a barrel, according to EU sanctions that came into effect on Monday.

The limit was put in place to curb revenues for Moscow while maintaining oil supplies.

  About 19 crude oil tankers were waiting to pass through Turkish waters on Friday, according to shipbrokers, oil traders and satellite tracking services.

The ships were docked near the Bosphorus and Dardanelles, which link Russia's Black Sea ports to international markets.

The first tanker arrived on Nov. 29 and had been waiting for six days, according to a shipbroker who declined to be named.

  Four oil executives said Turkey had asked for new proof of insurance given the oil price cap.

A spokesman for Turkey's transport ministry did not immediately respond to a request for comment.

  The tankers waiting in and around Turkish waters are the first sign that the oil price cap could disrupt global oil flows beyond Russian exports.

  On the 5th local time, the European Union's embargo on Russian seaborne oil came into effect.

Russian Deputy Prime Minister Novak said on the 4th that Russia will not comply with the price ceiling of $60 per barrel for Russian seaborne oil exports, and Russia will not supply oil to countries that set price ceilings.
