In recent years, the former internet elite has been dedicating to driving innovation in global health and development. As the Co-chair of the Bill & Melinda Gates Foundation, Gates decided to join force with China's Tsinghua University to establish the Global Health Drug Discovery Institute(GHDDI) in Beijing during his Davos visit.

"China has made incredible progress in reducing poverty and shares the foundation's commitment to harnessing advances in science and technology to address the critical health challenges affecting the world's poorest people," Gates said.

"We are excited about GHDDI's potential to drive innovation in global health research and development, and look forward to partnering with Tsinghua University on our continued work to address the world's most pressing global health challenges."

In an article released during WEF, Gates pledged his foundation would invest more in innovation in the coming years. He told Xinhua that the investment that went to China's innovation was expected to increase gradually.

Asked whether he worried about China's economic slowdown, which may hinder innovation progress, Gates said he was quite optimistic about China's economic outlook.

"I have a lot of confidence in China, partly because they take a long-term view, and partly because they look what other countries are doing," he said.

Faced with a challenge of turning the economy into new directions, Gates said China had great talent to achieve its goal.

"Most countries would envy a 6.9 percent growth, I think China has a bright future,"he said, adding "China is going to be contributing more and more to the world's innovation."
