More than 2,000 people took part on Wednesday in a procession to escort a relic of the Buddha lent by China to a shrine in the Thai capital Bangkok to mark the birthday of King Maha Vajiralongkorn and to celebrate half a century of diplomatic relations between Thailand and China. The tooth relic, considered sacred by Buddhists, was flown in earlier in the day from the Lingguang Temple in Beijing, which normally houses it.
