W: Sit down, please, Mr. Black. I hope you enjoyed your journey.
M: Of course, I did. It was a wonderful trip.
W: And I suspect this morning we’d like to get down to business. How would you like to proceed with the negotiations?
M: I’m here at your disposal.
W: Let’s draw up an agenda for our discussion, shall we?
M: Fine. One of the items for our agenda would be the supply of computers to China in the second half of this year. [1] /[2] As you know, our current contract is about to expire, and we will need to discuss a new one.
W: Certainly, we are ready to hear your proposals.
M: Something else I’d like to discuss is the possibility of establishing a long-term agreement between my corporation and yours.
W: Yes. So long as it’s in the interest of both sides, let’s talk about it. Is there anything else you’d like to achieve on this visit?
M: Yes. [2] I’d like to build on the fact that we have had a very cooperative relationship in the past few years. Your government now has a policy of opening up to the outside world. My ambition is to promote trade between our two corporations. It is said a new policy is being put into practice in your foreign trade. Is that true?
W: Yes, but we still stick to a consistent policy in our foreign trade [3] We insist on the principle of equality and mutual benefit, as well as exchanging needed goods.
M: Would you give us a brief account of the new practices you have adopted?
W: [4] We have adopted, for example, payment by installments.
M: We are very glad that you have such a friendly attitude.
W: It’ll benefit both of us.
