Are you talking about the British East India Company & The British Monarchs?
No, he's talking about the Sackler family:

Did the British East India company start the first Opium war?
I presume the British East India Company was managed by the British Monarchs
Did the British Monarchs claim to originate in Britain?
I do not see what that has to do with that other place unless they claim they came from that other place & not Britain
It is not like people can just make up where ever they want to & tell people they came from there & that gives them a divine mandate to rule
