In what way, Julio? I'm thinking of the major anti-imperialist movements which emerged in India, Algeria, Vietnam, Cuba, South Africa, Palestine and elsewhere in Asia, Africa, and Latin America and I'm having a hard time recalling any of them as having equated "Western imperialism" with the "white race", which is what your comment about "overlap" suggests.
In fact, these movements were dominated by socialists who were more apt to link imperialism to "capitalism" rather than to race, though of course they and their followers could not but be cognizant that the settlers they were fighting were white Europeans.
This did not deter them, however, from soliciting and welcoming solidarity and active support from within these settler communities. Where parties emerged within the liberation movements which did frame the struggle in racial terms - the most notable example perhaps being the Pan Africanist Congress (PAC) which bitterly opposed the multiracial ANC in South Africa - they remained in the minority.
