An unusual series of military exercises by Chinese warships in the sea between Australia and New Zealand has prompted reproval from leaders in both countries about the amount of warning given

New Zealand raised fresh concerns Monday over nearby live-fire drills conducted by Chinese warships armed with “extremely capable” weapons, an unprecedented show of firepower last week that analysts say are part of Beijing’s ongoing plan to build a blue-water navy with global reach.

New Zealand said the Chinese navy conducted a live-fire exercise in international waters near the Pacific nation on Saturday, a day after it held a similar drill between Australia and New Zealand that forced airlines to divert flights.

China conducted naval drills between Australia and New Zealand over two days. China on Sunday dismissed Australia's allegations that it did not give adequate notice before conducting naval drills in international waters.

Airlines have been contacted by Australia’s air traffic control agency warning them of reports of live fire off the country’s east coast where a Chinese navy task group has been operating, the agency and Australian officials said.
