A series of promotional videos starring the G20 Hangzhou Summit is being shown on a billboard-sized screen in New York's Times Square.

The series consists of three films, introducing China and the G20 Summit to tourists from around the world.

The 90-second video China Connecting With You G20 depicts China's efforts to combat the global financial crisis and push for economic growth.

Economists from UBS, ANZ (Australia and New Zealand banking group) and the London School of Economics comment in the video. They talk of the role that China plays in revitalizing the world economy and its strategy to revitalize the ancient Silk Road and head up the Asian Infrastructure Investment Bank (AIIB).

"It's quite true that a lot of emerging countries in the world are having enormous economic problems at the moment. China's role in international bodies like the G20 is really, really important in understanding the nature of the issues and what the collective solutions might be," George Magnus, senior economic adviser for UBS, says in the video.

"China has a lot to offer in terms of ideas, solutions, innovative approaches," says Garrick Hileman, economic historian at the University of Cambridge and London School of Economics. "And I see China is now playing a much more significant role in creating. It is opening its economy as [much as] possible."

"China is the model for all the developing nations in the world. The 21st century is going to be the century of China," says famed investor Jim Rogers, author of Street Smarts: Adventures on the Road and in the Markets.

The 90-second China's Responsibility for G20 stresses the importance of building a cooperative, mutual-gain global partnership.

It introduces that China signals her commitment to member nations and beyond through the megaproject the Belt and Road Initiative, AIIB and South-South Cooperation.
