Chinese Politics On African Cinderella's

Does anyone have more information on these stamps? I have four stamps, from Chad, Ivory Coast, Malawi and Djibouti and they all contain images of the Diaoyu Islands, claiming they are Chinese. This is a geopolitics on the mm. I am sure they are not real, but who would publish these and why stamps???

Hello;
They look real to me.

But they are not listed by catalogs.

Various governments have signed deals with various printers to create and sell stamps; then those countries are not really in control of what the printer prints. There are questions of just who (dictator? post office? postmaster general? rebel group? all 4?) ordered what from whom. I forget what country (Djibouti?) had two printers churning out different issues but almost none were recognized by anyone as legitimate. And just because a government has been overthrown or changed doesn't mean the old printing contract isn't interpreted by a printer to be still valid.

China is a huge investor in African infrastructure. It is no wonder that these countries (or whoever is in charge) would take a side on issues that don't involve them directly.
