China and the United States reached some important agreements and understandings regarding cybersecurity last month, but a lot of people are worried that it was all just meaningless talk with no real substance. While those concerns are still there, and still valid, the Chinese government’s recent decision to arrest hackers within its borders at the request of the United States definitely lends weight to the agreement. This marks the first time that China has actually arrested hackers that conducted cyberattacks against American corporations, and hopefully it won’t be the last.
