He adds that he has already invited the NCPA orchestra to perform in Canada next November.

"We see that arts and culture are an important way to express and represent China to the world," says Chen Ping, NCPA's president. "Through the agreement between NCPA and NAC, we would strengthen the bilateral relationship between the two countries."

Founded in 1969, the NAC is Canada's only bilingual multidisciplinary performing arts center. It is a leader in new media outreach in the arts and has created website nacotour.ca, where people around the world can follow its classes and concerts. Zukerman has given dozens of online classes to students outside Canada.

"Music has no boundary, and music is the language that is understood by people from every corner of the world. I demonstrate the gesture in front of the video in Ottawa then students in China or anywhere can see," says the maestro.

"The most important thing we can do in any relationship with any country is bring them what we do best," he says. "In my case I know how to play the fiddle and make music. So I bring that to China with an open heart and an abundance of feeling."

Among the orchestra are She Xiaoxue, a 28-year-old violinist from Shenyang, China, and Shi Shuai, 24, from Shanghai, who are both apprentices in the NAC Orchestra's 2013-2014 Institute for Orchestral Studies. Shi also assists Zukerman with his master classes in Beijing and Shanghai.
