SCO has also been promoting synergy between the Belt and Road cooperation and the development strategies of various countries and regional cooperation initiatives.

In May 2015, China and Russia signed a joint declaration of the connection of the Silk Road Economic Belt and the Eurasian Economic Union.

China and Kazakhstan have also found common goals by synergizing the initiative and Kazakh's economic plan, known as "Nurly Zhol" (meaning "bright path").

The BRI also accelerates cooperation between China and Uzbekistan, which offered the desired opportunity for Uzbekistan to improve its inter-connectivity with the outside world and play a greater role in wider regional development.
