"Connectivity, data access is too important to keep it only to the world's rich. There are 4 billion people in the world who don't have access, and when they get access they are more highly educated, they have job opportunities, and they have longer, healthier, more productive lives."
"And importantly, it's not just what they get from us because they can be connected to data, it's what we get from them. We get the benefit of their ideas."
"2016 is going to be a year where many, many market levels will be tested because opinion is divided, there's some real issues, there's some challenges, but I always like years which start badly because opportunities start to open up."

"We have to treat newcomers, refugees as human beings. People want to come to Europe to have a better, more secure life and we have to respect their will but we have to look at how sustainable the current influx is."
"The mood at the beginning of Davos is a bit gloomy, because everybody is looking at the stock price, the refugees, the security and the emerging markets.

"The situation in Syria is a breeding ground for terrorism for the whole world. We have seen what happened in Istanbul, in Paris, in Jakarta.

"China has been slowing down for years and will continue to slow down."

"It is bad news; it is entirely avoidable with the right policies, but the Chinese authorities are not yet ready to implement these right policies."
"I think some jitters are really jitters about jitters and some are really wondering about fundamentals," on the turmoil in markets.
"We understand that there may be no limit to what the ECB is willing to do but there is a very clear limit to what QE can and will achieve."
"And that's the problem. The problem is that monetary policy has largely run its course."
