[EX Q]: Lagos, Nigeria (CNN) Facebook founder Mark Zuckerberg's visit to Nigeria, his first to sub-Saharan Africa, has put the country's tech businesses firmly in the world's spotlight. Zuckerberg staged a surprise visit to the country's economic capital Lagos on Tuesday and his first stop was a local innovation center and tech hub in Yaba, an area on the mainland of Lagos known as Nigeria's Silicon Valley. There was no fanfare amid tight security and some of those working at the Co-Creation Hub, called CcHUB, didn't even know Zuckberg was coming. He appeared nervous, a little startled even, as he launched into an impromptu speech about why he was there.Zuckerberg causes a stir with surprise visit to Nigeria on TuesdayEntrepreneurs say it will give country's startup industry a boost

[EX Q]: (CNN) The 10-minute conversation between US President-elect Donald Trump and Taiwan President Tsai Ing-wen was a major break in the accepted protocol -- something that evidently does not much bother Mr. Trump. It is, of course, too soon to guess whether it was a fluke or a portent of a sea change in American policy. When the Communists won power on the mainland in 1949 their defeated Nationalist foes retreated to the island of Taiwan, either to go down in a last stand or to "recover the mainland." The Communists, for their part, determined to "liberate Taiwan." Both sides considered the standoff to be part of a continued civil war. Both claimed legitimate rule over all of China, with Taiwan merely a province of China. The one thing both agreed on was that Taiwan was inextricably part of China, and was not and could not be an independent country.Donald Trump's phone call with Taiwan was a major break in protocol, writes Peter MoodyMoody: It is too soon to say whether it means a sea change in US policy
