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.

Australia's defense forces, joined by New Zealand, have been monitoring Chinese navy vessels since they were spotted last week.

Airliners were over the Tasman Sea crossing between Australia and New Zealand when the Chinese navy warned they were flying over a secret live-fire exercise, Australian Defense Minister Richard Marles said on Friday.
