The presidency of Interpol is a largely honorific post, not an executive one at all. There is a precedent for the current case : a former President, from South Africa, was recalled and jailed for corruption.

Meng Hongwei was atypical in that he lived at Interpol HQ (occasional visits was the norm for previous Presidents). What's more, his wife and children lived with him in Lyon, and still do.

China had considerably increased its contribution to Interpol, this was concomitant with the election of Meng Hongwei. It is speculated that the CCP/Government overestimated the purchase that the presidency would give them over such matters as the publication by Interpol of arrest notices issued by the Chinese government... Anything that looks political is, still, politely declined by the bureaucracy.

So most likely he was recalled for not getting value for money, and perhaps for refusing (or being unable) to act on specific cases.
