so, ladies and gentlemen please welcome very cordially his excellency premier li keqiang, of the people's republic of china. >> professor klaus schwab, president, excellencies, ladies and gentlemen, dear friends, it gives me great pleasure to come back to davos after five years and deliver this address on the podium. this morning i had some spare time out of the official program of my visit so i took a bit of hiking nearby. the town of davos looks beautiful, tranquil and peaceful from atop of the mountain. yet the world outside is not a tranquil place. and it is not peaceful. so we need to jointly find ways to adapt to this new global context. last night professor schwab told me that davos used to be a place for recuperation from lung disease. however, because of the invention of penicillin, davos had transformed its function from lung to brain. today davos has become one of the world centers for brain-storming. we need new penicillin to treat new challenges in the international situation. the world today is anything but trubl-free. regional hot spots local conflicts and terrorist attack
