The DRC, Western powers and a UN expert group said the Tutsi-led rebel group is supported by Rwanda. Rwanda has denied all involvement, but the accusations have led to a diplomatic crisis in the region.

Above is a paragraph from the article you linked. Where does it say about this being to quote you “USA and Europe funded”.

Can you link information about this alleged involvement? From google searches all I can see is articles about US and EU telling Rwanda to stop funding this rebel group.
