China has applied for frequency and orbital resources for over 203,000 satellites across 14 constellations, fueling earlier gains in these sectors.
However, investors booked profits on Tuesday, with notable declines from China Spacesat (-1%), China Aerospace (-8.7%) and Addsino Co (-10%).
Meanwhile, artificial intelligence-linked shares continued to rise, including BlueFocus Intelligent (1%), Shanghai Stonehill (6.2%) and Zhongji Innolight (1.2%).
