The following topics are further illustrated: "The main terms of economic contracts" (经济合同的主要条款); "Economic contract signing" (经济合同签订); "Guarantee of economic contract" (经济合同的担保); "Conditions for the invalidity of economic contracts" (经济合同无效的条件); "Performance of economic contracts" (经济合同的履行); and "Signing economic contracts according to legal procedures" (按法定程序签订经济合同).
