In a statement, the group said the "reactivation" of the Red Notice against Mr Watson "is politically motivated and coincides with the launch of a newly-built factory whale processing vessel".

The study, Nutrient-delivery and metabolism reactivation therapy for melanoma, was led by Professor Wenbo Bu from Fudan University and Professor Dayong Jin from the University of Technology Sydney, and recently published in the journal Nature Nanotechnology.

The reactivation of melanin synthesis forces the melanoma cell to reduce glycolysis, the process of converting sugar to energy, which is believed to be the mechanism for its anti-cancer effect.
