On May 4, a side event under the framework of the 7th UN STI Forum, was hosted to engage representatives from multi-stakeholders including leadinguniversities, global publishers, NGOs and academics to explore the interaction between ‘open science’ and ‘quality graduate education’ in Global South under South-South collaborations. Stimulating dialogue was addressed for all the panelists to forge a consensus over the concept of open science on graduate education in Global South and deliver valuable recommendations on next steps, with an emphasis on leaving no one behind.
