People hold signs in support of jailed darknet market Silk Road founder Ross Ulbricht, as former President Trump attends the Libertarian Party's national convention in Washington, D.C., May 25, 2024.

French President Emmanuel Macron urged Europe Monday to take part in Chinas Silk Road revival plan, despite some European misgivings about the massive project, as he began a state visit.

Ulbricht, 40, received a life sentence without the possibility of parole in 2015 for creating Silk Road, an online marketplace that sold illegal drugs such as cocaine and heroin.
