Well, your own settlement in a foreign country falls under the definition. For me, at least. You can also look up the Boxer Rebellion for military action..

No, it doesn't. The Concessions were not military action, they were the results of diplomatic chicanery following the British fucking China over in the Opium Wars. The Boxer Rebellion was also not an invasion. It was more colonialist bullshit for sure, but it was not an invasion.

'Initially in 1854 a Yangtze Patrol was formed by ships of the USN East India Squadron but in 1868 this changed to the Asiatic Squadron.' navyhistory.au/the-united-s... But yeah, invasion like full military boots on the ground didn't happen. For me the above also counts, though..

that was decades before the boxers. so basically as long as "invasion" doesn't actually mean anything, then yes, they invaded.
