Soon after he founded the quarterly cultural review Naked Punch[2] together with contributors such as Noam Chomsky, Gayatry Spivak and Jacques Ranciere.

After spending time in China and obtaining a second degree from the School of Oriental and African Studies he launched Transnational Dialogues,[3] an exchange program between Chinese and European artists and activists.

Marsili appears as a guest on Italian national TV (Rai3 and La7), Al Jazeera and was host of TalkReal, a nomadic Europe-wide talk show.

[10] In his books Planetary Politics and La tua patria è il mondo intero (Your motherland is the entire world), he outlines a comprehensive transnational vision merging European cosmopolitanism with Chinese thought.

In the light of the COVID-19 pandemic in May 2020, Marsili called for a "European republic of equals" where every citizen could enjoy the same social protections, benefit from the same economic support and pay the same taxes.
