The State Council Measures on the Payment of Litigation Costs. Property cases are charged cumulatively by tier; cases under simplified procedure pay half the filing fee.

The Loan Prime Rate is published by the National Interbank Funding Center on the 20th of each month (postponed on holidays). Historical rates are maintained accordingly.
