North Korea Tests Powerful New Rocket Engine
North Korea has tested a powerful new rocket engine, state media said Sunday, with leader Kim Jong-Un hailing the successful test as a "new birth" for the nation's rocket industry.
Media reports indicated the test was likely to have been timed to coincide with the visit of U.S Secretary of State Rex Tillerson to Beijing on Saturday, where he warned that regional tensions had reached a "dangerous level".
North Korea’s state news agency KCNA said Kim had overseen the operation, and "emphasized that the whole world will soon witness what eventful significance the great victory won today carries".
The news agency implied that North Korea might use the new engine to launch a rocket to put a satellite in orbit.
"The development and completion of a new-type high-thrust engine would help consolidate the scientific and technological foundation to match the world-level satellite delivery capability in the field of outer space development," KCNA reported.
"The leader noted that the success made in the current test marked a great event of historic significance as it declared a new birth of the Juche-based rocket industry."
This came as the U.S and China on Saturday pledged to work together to address the threat posed by North Korea's nuclear program.
