U.S. whistleblower Edward Snowden's Chinese edition of his new book has been censored, he said on Tuesday.
"The Chinese edition of my new book, #PermanentRecord, has just been censored," Snowden said on Twitter.
"This violates the publishing agreement, so I'm going to resist it the way I know best: it's time to blow the whistle," he added.
His new book Permanent Record was published by Macmillan Publishers last month.
"And before anyone asks, I will make exactly zero dollars from the Chinese edition of the book (because of the U.S. government lawsuit), but that's alright: I didn't write this book for money," he clarified.
Snowden asked for help from the readers in restoring the missing passages.
"If you can read simplified Chinese and another language Permanent Record has been translated into (or know someone who does), tag them on this thread and see if they can help restore the missing passages to the Chinese edition," he said.
Snowden, who leaked thousands of documents detailing a long-term surveillance program by the U.S. government, was granted asylum by Russia in 2013 after he was charged with espionage.
His residence permit in Russia was extended until 2020.
