Here's an interesting little chain of events. Could be coincidence. Just interesting to note the dates.
June 13: Tillerson set to head to Russia for economic forum.
June 15: Russia announces plans to sell shares in Rosneft to "strategic investors".
June 17: Putin suddenly becomes very optimistic about Russia's stagnant economy.
