Plea bargain
In China, a plea bargaining pilot scheme has been introduced by the Standing Committee of the National People's Congress in 2016. For defendants that faces jail terms of three years or below, agrees to plea guilty voluntarily and agree with prosecutors' crime and sentencing proposals, will be given mitigated punishments.
Plea
In the U.S. federal system, the court must also satisfy itself that there is a factual basis for the guilty plea. However, this safeguard may not be very effective, because the parties, having reached a plea agreement, may be reluctant to reveal any information that could disturb the agreement. When a plea agreement has been made, the judge's factual basis inquiry is usually perfunctory, and the standard for finding that the plea is factually based is very low.
