During the month of December 2025, so, with one year delay, Saudi Arabia also issued a stamp relative to the Solidarity with Gaza set. This new stamp has to be added to the [T20241129] stamp series of the same design that already included Algeria – Djibouti (November 11, 2024) – Jordan (November 28, 2024) – Libya (December 31, 2024) – Morocco – Oman – Qatar (November 28, 2024) – Syria (October 7, 2024) and Tunisia. Details (including exact date of issue) for this additional country are still missing.

Similarly, Sudan released three stamps at the occasion of the Arab Postal day, with the same design as the stamps proposed on August 3, 2025 [T20250803] by seven other countries (Algeria – Egypt – Iraq – Libya (2025) – Oman – Tunisia (August 4, 2025) and the United Arab Emirates). Exact date of issue remains unknown for these three new stamps (difference can be seen only at the level of the denomination).

Regarding the previously reported joint issue between Laos and Thailand [T20251219], the stamps from Laos had not been shown yet. Here is a first illustration showing clearly the twin character. However, it is still not clear if Laos issued a second stamp similar to the second stamp from Thailand.

Egypt and Portugal celebrated 50 years of diplomatic relationships on December 18, 2025 with souvenir sheets containing each a pair of stamps representing the Nile River and the Douro River. Details from the Egyptian souvenir sheet are missing. The Portuguese souvenir sheet, size 95×125 mm has been issued at 20,000 samples only.

We got also some information about a potential joint issue involving Jordan and India for stamps supposed to be issued on December 16, 2025, but so far nothing could be confirmed and no stamps have been seen. Also, we are still looking for the illustration and exact date of issue of the Uruguayan stamp produced jointly with Romania and showing horses. Similarly, there are no news so far, from the Vietnam stamps supposed to be issued in parallel of Cyprus on December 1, 2025. Latest information seems to confirm that the Cyprus stamps could remain unilateral.
