BEIJING (Reuters) - China hopes Australia will do more to bring stability to the Asia-Pacific region, foreign ministry spokeswoman Hua Chunying said on Thursday, responding to reports that Australia and the United States plan to develop hypersonic missiles. Australia will jointly develop hypersonic cruise missiles with the United States in a bid to counter similar weapons being developed by China and Russia, its defence minister, Linda Reynolds, has said.
