March 2008 UTC I don t think either article should be titled invasion for different reasons In the case of the British in 1904 I think that it does meet the narrow definition of an invasion so titling it an invasion would not be inaccurate However I think that as Alexwoods argues invasion also implies that the invader intends to occupy the country or something along those lines which was not the case in the Younghusband incident So expedition would be a preferable title In the case of the PLA in 1950 we have the opposite situation There is no doubt that they came to occupy But the term invasion means that we are talking about one country violating the territory of a separate country Wikipedia can not take sides on whether China and Tibet were separate countries in 1950 22 29 22
