First of all, the patent right is regional. If you don't get a Japanese patent, you can't protect the Japanese market. That is to say, since you don't have rights in Japan, you can't claim rights.
Second, if it is sold to China, then C infringes; If it is sold to the United States, D infringes. Otherwise there is no infringement.
Third, manufacturing and selling are only two kinds of infringements, and there may be other infringements.
