The parent poster is talking about the Younghusband expedition into Tibet of 1903[1], I don't think it is the boxer rebellion in which British Indian troops had no direct involvement(AFAIK) and also those events happened before 1901 establishment of the Nobel Prize, which is the time period OP cites as the starting time range.
To see the Tibetan military expedition as an invasion of China, means to accept the Qing dynasty and its successor states (ROC,PRC)claim of sovereignty and not suzerainty over Tibet. A claim at the time which was not recognized by other countries specifically Russia, Britain and also Tibet.
The refusal of Tibetan government to accept terms of treaties they were not party to directly (i.e. the ones Qing China signed) was the official reason stated for the invasion by the British.
Either way it is a deeply contentious topic never legally settled in the 1907 agreement and had implications both to that era and modern geopolitics. No one then or now is purely looking at merits of the arguments.
The points will end up into esoteric discussion on whether is kowtowing and kneeling are the same thing, or is acknowledging supremacy is same as sovereignty, or the differences between vassal state or autonomous region or protectorate or suzerain.
Also the views of the countries/entities (or their successors) have also changed including the Tibetan government-in-exile in the last 120 years.
My knowledge of history is at best a passing student at high school level, this kind of discussion requires deep understanding of relationship of states, and of Chinese culture and language during Qing dynasty i.e. professional expertise which I certainly don't have.

[1] My initial read was they meant either Arunachal Pradesh( South Tibet to the Chinese), Aksai Chin or the MacMohan line etc, but they clarified it wasn't the case.
The Boxer Protocol wasn't signed until September 01901 and involved permanently establishing a dozen foreign military bases inside China, so didn't, from my point of view, end the invasion. But it's true that the actual fighting was almost completely the previous year.
