BEIJING -- China unveiled on Saturday the principles, framework, and cooperation priorities and mechanisms in its Belt and Road Initiative in a bid to enhance regional connectivity and embrace a brighter future together.

The action plan, jointly released by the National Development and Reform Commission, Ministry of Foreign Affairs and Ministry of Commerce, offered insight in the China-initiated program's vision and endeavors.

The Belt and Road routes run through the continents of Asia, Europe and Africa, connecting the vibrant East Asia economic circle at one end and developed European economic circle at the other.

The Silk Road Economic Belt focuses on bringing together China, Central Asia, Russia and Europe (the Baltic); linking China with the Persian Gulf and the Mediterranean Sea through Central Asia and the Indian Ocean. The 21st-Century Maritime Silk Road is designed to go from China's coast to Europe through the South China Sea and the Indian Ocean in one route, and from China's coast through the South China Sea to the South Pacific in the other.h Following are the major events in the development of China's "Belt and Road" Initiative so far.

September 2013 -- The Silk Road Economic Belt concept was introduced by Chinese President Xi Jinping during his visit to Kazakhstan.

It was the first time the Chinese leadership mentioned the strategic vision.

October 2013 -- President Xi proposed building a close-knit China-ASEAN community and offered guidance on constructing a 21st Century Maritime Silk Road to promote maritime cooperation.

November 2013 -- The Third Plenary Session of the 18th Central Committee of the Communist Party of China called for accelerating infrastructure links among neighboring countries and facilitating the Belt and Road initiative.
