The China-Brazil Joint Laboratory for Space Weather (CBJLSW) has successfully been carrying out joint observations and data pooling of the meridian chain of the solar-terrestrial space environment in the western hemisphere, mostly from ground-based observations. Over these years, we have jointly explored and researched the solar-terrestrial space environment in the low latitudes of the eastern and western hemispheres, as well as personnel training, to build the basic framework of the International Meridian Circle Program, and to serve as a bridge and link for cultural exchanges between China and Brazil. Now, to contribute to exploring key scientific challenges and brainstorming future research paths, in the current presentation, we presented some scientific and technological challenges we would like to tackle in the coupling process from the solar-terrestrial perspective. Scientifically, considering a reactivation of sounding rocket research by several countries, we see opportunities for the E-region research close to the South American Magnetic Anomaly. Technologically, seeking to improve the BeiDou Navigation Satellite System accuracy as well as the other GNSS networks, we also propose to monitor Equatorial Plasma Bubbles with the use of the CBERS-5 Geostationary satellite.
