Problems existed in China-Africa political mutual trust at the conceptual level，especially at the level of value. Nowadays，there exists the problem of value identity between China and Africa，and it has also become one of the focuses of the game between the West and China in Africa. How to deal with the problems and challenges that Sino-African political mutual trust faces at the level of value，in other words，how to enhance China-Africa mutual political trust at the level of value deserves some consideration. The correct way to tackle the problem is not to avoid the issues that related to it，but to advance China-Africa political interaction directly from the aspect of value. Focusing on the main problems and finding out the right breakthrough point，twofold results could be yielded with half the effort in solving the problem. Given the fact that the problems in China-Africa political mutual trust in the value dimension relate，directly or indirectly，to the political democratization in Africa，it is necessary for China to review and evaluate them afresh with objective and rational attitude from the angle of overall national interests. This may be a crucial approach to tackle the crux of China-Africa political mutual trust. The result of the move may have double benefit：the political base of China-Africa cooperation can be consolidated and the Western offensive of “value diplomacy” in Africa may be dissolved.
