It is interesting, that China Initiative for cooperation with CEE countries, named "16+1" Initiative even originated before OBOR.

"16+1”Initiative was introduced in April 2012, almost one year before China officially announced “Silk Road Economic Belt and 21 st Century Maritime Silk Road” (referred as One belt one Road - OBOR) in September and October 2013.

CEE countries represent an end and beginning, that is, an opening window of opportunity for China “go west” connections to Europe, and vice versa. It is beginning of OBOR from Europe to China. Thus “16+1 Initiative” is seen as important part of China vast project, connecting three continents and several sub regions. When completed, like the ancient Silk Road, it will connect three continents: Asia, Europe, and Africa.
