China has reached another landmark in its quest for a fusion reactor with the latest experiment on an "artificial sun" last Friday in Hefei, Anhui Province.

The experimental advanced superconducting tokamak (EAST) broke the world record of achieving a plasma temperature of 120 million degree centigrade for 101 seconds.

The EAST also realized a plasma temperature of 160 million degrees Celsius, lasting for 20 seconds.

The ultimate goal of EAST is to create nuclear fusion like the Sun, using deuterium abound in the sea to provide a steady stream of clean energy. (ECNS)
