Mr Bambawale, other diplomats, staff of the embassy, yoga teachers and students of China's Yogi Yoga centre took part in the event. Over 500 yoga lovers turned up to take part in over hour-long special yoga workout at the old Indian embassy premises.
Every year large number of people participate in Yoga Day events in China since UN General Assembly declared June 21 as International Day of Yoga.
"I would say tens of thousands took part in China. But millions will be doing in their way either individually or in smaller groups," Mr Bambawale said.
The day is celebrated in 25 to 30 cities in different parts of China with larger turnouts, he said.
"Delighted that Yoga has become so popular in China. It helps in providing a bridge between India and China and bringing people of the two countries together," he said.
"It shows how yoga is spread widely in China. The reason is not because of anything else but because ordinary people in China like other parts of the world are beginning to realise that yoga is contributing to making their lives successful both at the personal and professional level. It is undeniable fact", he said
The popularity of Yoga is going to increase not only in India but also in China, he said.
