China’s Great Firewall blocks social media platforms like Facebook and TikTok, along with certain political topics, streaming platforms, and even Google. For years, we’ve heard about what China’s firewall keeps out — but much less about how it’s achieved. Now, a massive leak is shedding light on how the country’s censorship technology works and which countries it’s being exported to.

Today, the Globe’s Asia Correspondent, James Griffiths is here. He’s an expert on China’s online censorship, and he’s the author of The Great Firewall of China. He’ll explain what the leak exposes, which countries China is replicating its firewall in, and what it all means for the country’s growing global influence.
