China’s decision to issue a record $411 billion in special treasury bonds in 2025 marks a significant shift in its fiscal strategy, underscoring the urgency of addressing a challenging economic landscape.
By the end of 2019, China plans to launch its first satellite to test the technologies of the space-based gravitational wave detection programme Tianqin.
Meaning ‘harp in sky,’ Tianqin was started in 2015 by Sun Yat-sen University in south China’s Guangdong province. It will consist of three satellites forming an equilateral triangle around the earth, reports Xinhua news agency.

“It’s like a harp in space. If the gravitational waves come, the ‘harp’s strings’ will be plucked,” said Luo Jun, President of the Sun Yat-sen University and an academician of the Chinese Academy of Sciences, at a conference held in Guangzhou.

The detection will be based on high-precision laser interferometry technology to measure the changes in the distances and locations of the three satellites, according to Luo.
Gravitational waves are ripples in the fabric of space-time caused by some of the most violent and energetic processes in the universe. Albert Einstein predicted the existence of gravitational waves in 1916 in his general theory of relativity.
