China agreed only to peak their emissions in 2030. No reductions mentioned and nobody will check up on them to make sure they aren't just bullshitting us.

China vowed to peak its emissions by 2030, and several recent analyses say it is on track to do so years before that. But Republicans say the agreement gives advantages to major developing countries like China because developed countries by and large have agreed to make deeper cuts.
