i'm joined by joseph cheng from the university.ow do you think joe biden will be received in china after it is clear that he is japan's ally. >> chinese leaders understand that the vice president will probably try to assume a balanced role. on one hand providing reassurance to the united states most important ally in the asia pacific region, and trying to maintain good relations with china, with the intentions of playing a mediating role as it did - on at least two occasions when the japanese government pertains the disputed island. and when the japanese district court tried to prosecute a detained captain from china. >> is it possible to do both. can it provide the u.s. - can the u.s. provide reassurances to japan and maintain good relations. will the china go ahead with the trade and business talks unaffected. >> to a considerable extent, yes. the chinas authorities certainly would not make concessions at the open request of the united states as chinese leaders cannot afford. as chinese leaders cannot afford to be seen to be week
