The programme of new stamps from Belarus included a potential joint issue with China and another with Vietnam, both expected to be released during the month of January at the occasion of the 30th anniversary of diplomatic relationships. The Belarus stamps were issued respectively on January 12, 2022 and January 24, 2022, but there is absolutely no news from either China PR nor Vietnam for event-associated stamps. There are great chances that these issues will remain unilateral and that the entries will have to be removed from the list described in the catalogue (Vol 15). At least, here are the pictures of the Belarus stamps.
An other opportunity was mentioned by Cesar Ittman (The Netherlands). During the year 2022, France celebrates the 200th anniversary of the death of the famous author Moliere. France issued a first stamp on January 17, 2022, at the same time as Monaco, while Czech Republic issued a stamp on January 20, 2022. There is absolutely no claim from one of these countries for a joint issue. These are just stamps issued at the occasion of an anniversary and it would not be surprising to see much more other stamps released to honor Moliere during this year without any joint character.
The first true joint issue to be released this year is scheduled for February 14, 2022, not earlier. This is quite late compared to previous years.
Don Birschel (USA) explored older issues and asked about the relevance of some 2006 China-Africa Forum stamps as joint. Indeed, some of these stamps show the same design, but this is a logo and none of the countries have claimed a joint issue character. So again, this is an exemple of a non-approved joint issue. Here are the pictures of the stamps from countries that celebrated this event: Algeria (November 6, 2006), China (November 3), Egypt (November 5), Eritrea (November 3) and Ivory Coast (November 28).
