Politics is a game of balance, Now i guess felix is balancing all the aspect for his election,
China is a very important political, business, and strategic partner for DRC, and no matter how bad they are, he still need to keep them.
If he kicks China out now,
he might lose his election campaign,
trade volume will drop dramatically in the short term, and it will affect his reputation for presidential election as well.
China has been in Africa for decades and has too much influence over their ministers and citizens. he need to avoid to do that now.
At the same time, Felix need new partners , such as Westerners, Australians, Koreans, Japanese, etc., that's the reason why he travel around the world to attract new investment. i guess he is now consolidate what they already have, then seek for new and better investors to create a better future for the DRC.
So I think felix will follow the ICC's results and act accordingly, to aviod to offend China.
China has never said they support corruption, so the ICC's decision will make it easier for felix to explain to the Chinese side.
and Following the ICC will also make new investors feel safe to invest in DRC.
Of course the above is all my speculation ....
