Meanwhile, a commemorative envelope was issued in Beijing on Monday, celebrating the 69th anniversary of diplomatic ties between China and India. Exchanges between the two started as early as the 1st Century A.D. The release also marks the upcoming 70th birthday of the People's Republic of China. Our reporter Yang Ran tells us more.

Wang Hua, representing the China Foundation for Peace and Development and Acquino Vimal, the Indian Embassy's Deputy Chief of Missions, unveiled the envelope.

The stamp on the envelope, named the "Peace Angels," is jointly designed by Chinese artist Mao Daizong and Indian painter Shatrudhan K. Gupta. Graduating from the Art and Crafts College of Lucknow University in India, Gupta joined in the "Senior Scholar Research Project" of the China Academy of Art in 2016.  He drew the modern architecture and auspicious clouds on the canvas and Professor Mao Daizong of Shandong University of Arts added with Flying Apsarases.

ACQUINO VIMAL, DEPUTY CHIEF OF MISSION EMBASSY OF INDIA IN CHINA "I think the team is very good. They have brought a mix of modernity and certain historic value. They have two apsaras on the image which is from Dunhuang. I think it is a very good initiative to get the artists here and do this event."

India was the first non-socialist country who tied diplomatic relations with China. Mr. Wang Hua says the initiation is very special and it is going to be continued.

WANG HUA, DEPUTY SECRETARY GENERAL CHINA FOUNDATION FOR PEACE & DEVELOPMENT "2, 3 months ago, my workmates and I had a discussion and decided to celebrate the 70th birthday of the People's Republic of China in a rather traditional way. It is possibly the first time that we get renowned artists from both China and India together and combine their inspirations and complete an art piece. We wish we could finish 70 commemorative envelopes by the end of this year."

YANG RAN BEIJING "China has issued the commemorative envelopes with 8 countries including the Maldives, France, Russia, Costa Rica, Cuba, Uruguay, Colombia and Ecuador. YR, CGTN, BJ."
