While it is true that the eu got screwed by the us and the uk - there is no conspiracy wrt the temporary stoppage of the az roll out - the blood clots were first reported in Norway which is not in the eu.
Pretty sure this is wrong. The UK and the EU paid to set up separate supply chains for the AstraZeneca vaccine, with the UK having first dibs on the output of the UK one (which ended up with better yields, likely in part due to being agreed on and set up first). The EU kept on blaming AstraZeneca's failure to supply enough vaccines to EU countries on them exporting the EU-produced ones to the UK, but as far as I know there's no evidence that ever happened despite police raids on the production facilities and new requirements to get licenses to export vaccines. Also the numbers don't add up at all.
The AstraZeneca vaccine is also the only one with this kind of segregated supply chain, apparently as some kind of contingency plan against vaccine nationalism cutting off imports. All the others, the UK has been content to order from plants within the EU and trust that they won't pull some cynical, Trump-esque vaccine nationalism stunt and cut off exports to distract from their own problems. This appears to have been a serious misjudgement. (And to be clear, distracting from their own problems is pretty much all it would achieve. The UK is so much smaller than the EU that cutting off exports would give very little help to their own vaccine roll-out despite causing massive disruption to the UK one - and that's before even considering the possibility of retaliation.)

The UK is included in the contract of the EU the same way as the EU is included in the one of the EU. That's why there are discussions about the export of vaccine to begin with. Right now AZ exports a few millions of doses out of the EU to the UK.
