Definition: You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. If the conversation begins with a question, label it '1' otherwise '0'.
Input:  Person1:     Since China was open to the outside world , its trade forms have become much more flexible . One of these commonly used forms is co-production . Would you please do a bit explanation of it , Mr . Walker ?  
 Person2:  Well , under this arrangement two parties cooperate to manufacture a product or a category of products , for example , machine tools for export . Each party produces and supplies a part of the components and parts ; one party is a Chinese enterprise , the other , an overseas firm . Most probably , the foreign counterpart contributes technology and equipment , and sometimes , parts and components , while the Chinese enterprises factory building , labor and other resources to the cooperative production . They join hands and fulfill orders together by an agreement or a contract .  
 Person1:      I suppose that the assembling of these components and parts , particularly the marketing of the finished products should take place in China .  
 Person2:  Not necessarily . It depends on the contract stipulations . They may be marketed in the foreign country where the other party is located , or even in a third country .  
 Person1:      I think the principle of co-production is to expand export trade . It's a reciprocal business , isn't it ?  
 Person2:  Yes , you are right . Either party is not well-equipped to produce the final products single-handedly , but they can enter into an agreement . In such case , each side contributes different resources to make the manufacture of a certain product or a category of products possible .
