guy monson is still here with us.seems the americans are trying to pressure china in various ways. president trump taking to twitter, as he does. geopolitics in this region, is this something that worries you in itself for stability in the region or is it simply a distraction from what you would rather washington were getting on with? guy: i think it's the secondary effects that worry us. was a possible buildup is what stands behind the trump tweet is a possible move toward sector -- secondary sanctions that hit chinese financial services firms and companies that trade directly with the north korean regime. that will be messy but it's clearly one of the few available screws the americans have to tighten pressure on north korea. so were not building in north korea event risk yet but possible damage to some u.s. relations. anna: those have already been damaged by all the conversations during the election campaign around trade but that hasn't yet manifested itself on a large-scale cents president trump has been elected.
