Trump's Sec. of State nominee used to direct Exxon's Russian subsidiary, still owns stock, leaked document reveals

Rex Tillerson, the businessman nominated by Donald Trump to be the next US secretary of state, was the long-time director of a US-Russian oil firm based in the tax haven of the Bahamas, leaked documents show.

Tillerson – the chief executive of ExxonMobil – became a director of the oil company’s Russian subsidiary, Exxon Neftegas, in 1998. His name – RW Tillerson – appears next to other officers who are based at Houston, Texas; Moscow; and Sakhalin, in Russia’s far east.

The leaked 2001 document comes from the corporate registry in the Bahamas. It was one of 1.3m files given to the Germany newspaper Süddeutsche Zeitung by an anonymous source. The registry is public but details of individual directors are typically incomplete or missing entirely.

Though there is nothing untoward about this directorship, it has not been reported before and is likely to raise fresh questions over Tillerson’s relationship with Russia ahead of a potentially stormy confirmation hearing by the US senate foreign relations committee. Exxon said on Sunday that Tillerson was no longer a director after becoming the company’s CEO in 2006.

ExxonMobil’s use of offshore regimes – while legal – may also jar with Trump’s avowal to put “America first”.

Tillerson’s critics say he is too close to the Russian president, Vladimir Putin, and that his appointment could raise potential conflicts of interest.

ExxonMobil is the world’s largest oil company and has for a long time been eyeing Russia’s vast oil and gas deposits. Tillerson currently has Exxon stock worth more than $200m.
