The 20th G20 summit will be held in Johannesburg, South Africa, from November 22 to 23, marking the first time the summit has taken place in Africa. The theme is "Solidarity, Equality and Sustainability."

In this video, British vlogger Luke shares his expectations for the summit. Citing China's global leadership in AI through its strong performance in papers, patents and start-ups, as well as its unique environment of close integration between industry, academia and research, Luke explains why he chose to pursue a doctoral degree in AI in China. Unlike Western AI companies, he notes, Chinese firms emphasize collaboration and applying research results to social development. For this year's G20 summit, Luke hopes to see strengthened cooperation among G20 members in key areas, including artificial intelligence.
