Brunei in China's 15th ASEAN-China Dialogue Cooperation Miniature Sheet 2006
In 2006, China and ASEAN celebrated its 15th Anniversary of ASEAN-China Dialogue Cooperation. China issued a special stamp as well as two miniature sheets commemorating the occasion. This first miniature sheet depicts all the heritage of the ASEAN member states. It was hard to find Brunei but it is on the top row, the third stamp. I took the liberty of enlarging just that stamp:
It is the Royal Chariot that is currently on display at the Royal Regalia Museum in Bandar Seri Begawan.
