Guo Degang, a popular Chinese traditional crosstalk performer, signed a letter of agreement here on Thursday with the National Museum of Australia (NWA) to become the museum's cultural ambassador in China.

At the signing ceremony held at the NWA, Guo said he was honored to take the role.

Under the agreement, Guo will promote the NMA's programs in China, the first of which will be a major exhibition of bark paintings on tour in China starting from July this year.

The Old Masters exhibition featuring over 150 artworks and objects will open at the National Museum of China in Beijing in July 2018, ahead of a 20-month tour. It will later open in cities including Shanghai, Chengdu and Shenzhen, among others.

It will be the first time that the bark paintings be exhibited outside Australia.

Guo, a leading character in China's traditional crosstalk comedy and a household name in China, enjoys more than 68 million followers on social media site Weibo.

"Arts recognize no boundaries ... I think art is a very good bond to link people together and promote exchanges," Guo told Xinhua at the signing ceremony.

NWA Director Mathew Trinca said he found common ground in Guo's love of traditional Chinese art and his museum's enthusiasm in collecting and promoting Australia's traditional art.

"The National Museum is committed to taking the Australian story to the world and we're delighted to partner with Mr Guo to help us reach Chinese audiences," said Trinca.
