Having originally been destined for Qingdao, the largest crude import terminal in China, a Greek VLCC laden with Venezuelan oil took a U-turn in mid-January.

Dynacom Tankers Management’s 318,300-dwt Ioanna (built 2008) then stopped transmitting AIS signals for more than a week in the East China Sea, before reappearing northeast of Taiwan in early February.

The vessel was then sailing towards Zhanjiang, another oil terminal in China, according to several vessel-tracking databases.
