The region is controlled by Guyana, which is a puppet regime of the US. Exxon mobile currently has operations in the region, which has a high risk of being environmentally devastating. Nobody wants them to be there except the US and Guyana by extension.

The region is currently disputed between Guyana and Venezuela, over some old borders the British drew up. So, Venezuela is using that to send cease and desist letters to Exxon.

The US not only has interest in the area over Exxon Mobil but also they want to annex Venezuela and replace the Maduro gov.

And as such, the US IS ready to build a military base in the disputed region to start operations.

And THAT is why there’s discussion about how Venezuela wants to annex the region.

Upon further research, the areas of dispute are maritime borders, within Venezuela’s exclusive economic zone.

So, in addition to the above, Exxon is stealing Venezuela’s oil reserves.

Superimposed maritime boundaries to oilfield blocks.
