China will send its highest-level delegation since 2009 to Davos, Switzerland, to attend the annual World Economic Forum as part of its effort to boost its presence in global affairs and woo international investors amid an economic downturn.

Premier Li Keqiang will be in Davos for the forum from Jan 20 to 22, a Foreign Ministry spokesman announced on Tuesday.

Li will deliver a speech and meet with representatives of the International Business Council. He will also meet Klaus Schwab, chairman of the forum, spokesman Hong Lei said at a daily news briefing.
