The existence of embassies, ambassadors and non-Muslims' investment authorities in Muslim countries is apostasy as it is deemed to be a kind of loyalty to non-Muslims; Allah says," Let not believers take disbelievers as allies rather than believers. And whoever [of you] does that has nothing with Allah, except when taking precaution against them in prudence. And Allah warns you of Himself and to Allah is the [final] destination". There are many verses forbidding loyalty to non-Muslims.
