Australia asks China to explain 'extraordinary' military build-up

Australia's Defence Minister questions China's "extraordinary" military build-up at the Shangri-la Dialogue in Singapore. Meanwhile, the Philippines Defence Minister criticizes China's actions in the South China Sea as "irresponsible and reckless." China has not responded to the concerns raised by either minister. The dialogue, hosted by the International Institute for Strategic Studies, highlighted the growing tensions between the US and China in the region.
