Chinese Premier Li Keqiang will attend a summit of European and Asian leaders on a trip starting this week that will also include a visit to Germany and the signing of energy and high-speed rail deals with Russia, the Chinese government said.

Li's Oct. 9-16 swing through the continent is his second this year, and will culminate in the Asia-Europe Meeting summit in Milan, Italy, the Chinese Foreign Ministry said in a statement.

It takes place as the former British colony of Hong Kong has been rocked by pro-democracy demonstrations and also as the European Union steps up sanctions on Russia over the crisis in Ukraine.
