What is the point of diplomacy with teeth that does not include oil trading? The Chinese have clearly stated, that they will not be party to any aggreement, that would stop the flow of oil. And then you have the UK being the centre of military precurement. Unlike the US, the UK is not forcing companies to choose between the Seyyeds and UK.
