The stamps were on a waiting list since April 28, 2023, and, finally, they became officially available on October 16, 2023. Since beginning of the year, the India – Vietnam joint issue went through several hickups starting with the isolated release of the Vietnamese stamps at a single postal office on the official initial April 28 date, but was quickly retrieved from sale after apparently 4,000 samples were sold. In the meantime, India announced several intermediate release dates until it came to a real availability this week (Information provided simultaneously by Kenneth Sequeira, Singapore and Souvik Ghatak, India). As a consequence of this earlier accidental availability, this series will be filed as concerted issue [C] rather than Twin [T].

These stamps celebrate the 50th anniversary of the diplomatic relationship between both countries, which actually goes back to January 7, 2022, with illustrations of local fighting sports. Vietnam introduces the martial art Vovinam and India introduces the martial art Kalarippayattu. The Vietnamese stamps are available in panes (total 5,400 sets), booklet of 4 pairs, imperforate stamps (1,800 sets) and specimen overprinted stamps (1,300 sets). India has released stamps in panes and souvenir sheets, but details are awaited.
