MANILA, Philippines — Expressing concern over the scale of China's activities in the disputed South China Sea, Australia urged all claimants to clarify the full nature of their claims in accordance with international law.

In its 2017 Foreign Policy White Paper released a few weeks ago, Australia stressed its position that the UN-backed tribunal's ruling on the Philippines' arbitration case against China is "final and binding on both parties."

Clarifying that they are not taking sides in the competing claims, Australia considers the South China Sea as a "major fault line" in the regional order.

"Like other non-claimant states, however, we have a substantial interest in the stability of this crucial international waterway, and in the norms and laws that govern it," the Foreign Policy White Paper read.

Australia noted that they have urged all claimants to refrain from actions that would increase tension in the region. They have also called for a halt on Beijing's land reclamation and construction activities.

Resolving dispute should be based on international law, in accordance with the United Nations Convention on the Law of the Sea (UNCLOS), Australia said in its foreign policy paper.

"Australia opposes the use of disputed features and artificial structures in the South China Sea for military purposes," the white paper read.

The Australian government vowed to ensure international law, particularly UNCLOS, will be respected and implemented to protect freedom of navigation in the region.

Meanwhile, China criticized Australia for its "irresponsible comments" on the South China Sea.

Chinese Defense Ministry spokesperson Wu Qian stressed that Australia is not in a position to make comments on the contested waters as they are not a claimant country.

"It has been proven by facts that interference from countries outside the region can only complicate the South China Sea issue and will be of no help to regional peace and stability," Wu said in a press briefing.

Earlier this year, Beijing also slammed US Secretary Rex Tillerson for his comment that China is using its economic powers to buy its way out of problems.

"China is a significant economic and trading power, and we desire a productive relationship, but we cannot allow China to use its economic power to buy its way out of other problems, whether it’s militarizing islands in the South China Sea or failure to put appropriate pressure on North Korea," Tillerson said in Sydney last June.

Beijing had been insisting that the situation in the South China Sea has "cooled down" following direct consultations and dialogues with claimant states.
