China's 19th naval escort task force consisting of a Type 903 replenishment ship and two Type 054A guided-missile frigates entered the Black Sea through the Bosphorus on May 4.
Both frigates are of the type Jiangkai II-Class and are part of the Northern Fleet of the Chinese Navy, based in Qingdao.
The purpose of entry of the ships into the Black Sea waters is still unknown, as there are no reports of previous visits of the Chinese ships.
However, some media have reported that the frigates are headed to Novorossiysk to participate in activities in the connection with the 70th anniversary of victory over Nazi Germany and the end of World War II.
President Xi Jinping of China has accepted an invitation from President Vladimir Putin to attend the Victory Parade in Moscow and is due to arrive in Russia on 8 May.
