China's Foreign Ministry has delivered a sharp rebuke of the Australian Government's increased defence spend.

It comes after Defence Minister Richard Marles on Wednesday revealed the government would boost defence spending by $50 billion over the next decade.

Mr Marles has confirmed less than six per cent of the new funds will be spent in the next four years.

The Defence Minister also released the government's new defence strategy, warning China is looking to "change the current regional balance"

Beijing has responded by expressing a firm opposition to assertions of China's so-called 'coercive tactics'.
