The more I look into this stuff, the more I am convinced it was either the Americans or the Chinese under the auspices of the Biden admin.
Why: before the blowup, a Chinese owned company (Sinopec) in an unusual move, sets in fleets of new tankers to transport oil from the Middle East to Europe and China. This started months before the invasion by Russia and well above usual demand, while people were expecting small (9% increases) in volume following COVID, they are literally doubling their demand setting in orders for 40, then 10 and even more oil and LNG tankers, (https://www.hellenicshippingnews.com/unipec-buys-over-40-lng-cargoes-in-strip-tender-for-june-2021-feb-2022-sources/ ) many market watchers weren’t sure what it meant or why the company would do such an unusual thing. One article calls it “mysterious”. A few months later, Ukraine is invaded, Zelensky shuts down their connection between Europe and Russia, Nordstream blows up, suddenly the US is shipping 40% of its strategic oil reserve to China and Europe and Europe is demanding massive oil from the Saudis and Africa.
Who gets the majority of contracts, the company that recently purchased all the capacity on the market, Unipec, a subsidiary of Sinopec. Sinopec is wholly owned by the Chinese government. Meanwhile we recently found out from Republican House investigations that private equity firm, BHR Partners, founded and currently still held by the president’s son, Hunter Biden, invested $1.7 billion in Sinopec.
There is obviously no direct evidence, it just happens that Biden family investments always happen to make weird moves before major events and happen to always do very well when Joe is in some form of office.
