Pu was found guilty by a Beijing court for "inciting ethnic hatred" and "picking quarrels" in social media posts besides posting online comments critical of Communist Party.
Pu has been released from detention after receiving the suspended jail sentence, the BBC reported.
Earlier, a Beijing court handed down Pu a suspended three-year prison sentence for inciting ethnic hatred and disturbing public order.
The suspended sentence is a surprise as Pu could have faced a maximum sentence of eight years in prison.

Amnesty International said the suspended prison sentence was "a deliberate attempt by the Chinese authorities to shackle a champion of freedom of expression".
Experts say the suspended sentence means Pu can avoid serving time in jail, but could be monitored during the suspension period. The guilty verdict means he can no longer practice law.
Pu's lawyer Shang Baojun told South China Morning Post that his Advocate licence would be permanently revoked as lawyers who have been convicted are barred from practising by law.
"To be incriminated over one's speech in seven microblog messages- this is a very heavy price indeed," Shang said.
Pu's trial held on December 14 attracted international media attention as Chinese police in plainclothes scuffled with diplomats and foreign journalists outside the courtroom.
A large group of aggressive plainclothes policemen - many of them wearing yellow smiley-face badges - pushed, punched and harassed reporters, camera-crews and diplomats away from the front of the court.
One US diplomat, who had tried to attend court as an observer, was jostled along the street as he tried to read a statement condemning China's treatment of Pu.
