Taiwan worrying about war threat

China is ramping up the pressure on Taiwan, conducting military exercises off the coast and summarily removing an agreed median line in the Taiwan Straits which helped prevent military accidents. Opinion is divided as to whether Beijing is trying to provoke a reaction or to shake Taiwan’s morale and indicate displeasure about closer contacts between Taipei and Washington and a possible arms sales. Officials say it is the worst escalation of military activity in more than two decades.
