Inside the tranquil temple, King Maha Vajiralongkorn and Queen Suthida entered the main hall to pay homage to the Buddha.
After the royal couple offered candles and flowers, monks and Buddhist followers chanted prayers for their peace and well-being and for the continued development of relations between Thailand and Vietnam.

The pagoda has previously welcomed foreign dignitaries including the King of Cambodia and the Prime Minister of India.
Buddhism has a long history in Thailand, with its influence deeply embedded in the country's cultural and religious life.
During their visit, the King and Queen also spoke with senior leaders of the Vietnam Buddhist Sangha and wished them good health and peace.
Earlier Wednesday, King Maha Vajiralongkorn, Queen Suthida and the Thai royal delegation visited the Ho Chi Minh Mausoleum to pay respects to Vietnam's late president.
