The case is seen as a measure of how the Chinese authorities intend to use the new law, which has provoked protests around the world.

The law came into force at the turn of the month June-July last year.

And on July 1, Tong rode around on a motorcycle with a flag that read "Liberate Hong Kong - the revolution of our time".

That means he urged others to session, that is, to separate Hong Kong from China, according to the court.

Can get life

In combination with the fact that at the time he was plowing into a group of police with the motorcycle, he also committed a terrorist act, and is therefore guilty of both charges, the judges write.

He risks life imprisonment.

The security law itself has been criticized around the world as draconian, a way for the Beijing regime to dilute the freedoms enjoyed by Hong Kong people, rights that do not exist in the rest of China.

It has raised questions about whether Hong Kong can remain one of Asia's most important financial hubs, if foreign companies and business people feel that they can no longer trust the legal system.

Selected judges

How this trial was conducted is also controversial.

Unlike the practice in Hong Kong, the case has not been decided by a jury but by three judges.

They have been selected by Hong Kong's Beijing loyalist leader Carrie Lam, specifically for national security objectives.

After Tong, more than 60 others are awaiting trial in accordance with the new law.

Among them are several well-known names, such as Jimmy Lai, owner of the now defunct Apple Daily.
