XI'AN, April 23 -- A coalition was established Sunday in northwest China's Shaanxi Province to promote innovation and cooperation on space exploration under the the Belt and Road Initiative.

The coalition, set up in the provincial capital of Xi'an, encompasses 48 universities, research institutes and academic organizations at home and abroad. It was initiated by the Chinese Society of Astronautics and Xi'an-based Northwestern Polytechnical University.

Tian Yulong, secretary-general of China National Space Administration, said the alliance will boost exchanges on space innovation between its members and help joint training of high-caliber professionals.

China designated April 24 as Space Day last year to mark the anniversary of the country's first satellite launch Dongfanghong-1 in 1970.

Xi'an, home to more than 200 aerospace research centers and enterprises, will hold major celebrations on Monday.
