Cambodia and Beijing have denied a report that they are building a secret naval facility for the Chinese fleet, as Prime Minister Anthony Albanese voiced concern and called for transparency.
American newspaper The Washington Post, citing unnamed Western officials, said a new facility at Cambodia's Ream base - strategically located on the Gulf of Thailand - was being built for the "exclusive" use of the Chinese navy.
The base has been a running sore spot in United States-Cambodian relations for years, with the US long suspecting it is being converted for use by China as it seeks to buttress its international influence with a network of military outposts.

Earlier a spokesman had said the base's development was "not a secret".
"Cambodia won't allow the Chinese military to use it exclusively or to develop the site as its military base," government spokesman Phay Siphan told news agency AFP.
The Cambodian defence minister and China's ambassador will be attending a ground-breaking ceremony Wednesday for new facilities at Ream, including a boat repair shop and a pier.
But Mr Albanese, to counter growing Chinese assertiveness in the region, labelled the reports "concerning".
"We encourage Beijing to be transparent about its intent and to ensure that its activities support regional security and stability," he told reporters, saying Cambodia had assured Canberra that no foreign military would be given exclusive access to the Ream base.
Australia has grown increasingly worried about Beijing's growing influence in the Pacific region.
A leaked draft of a in April raised concerns that it would allow Chinese naval deployments to the Pacific island nation — less than 2,000 kilometres from Australia.
Denials from China, Cambodia
Prime Minister Hun Sen has repeatedly insisted the work is nothing more than modernising the base with a new boat maintenance facility developed with Chinese aid.
"Cambodia doesn't need the presence of a foreign military on its territory," he said in a speech last month.
China also denied that the base would be solely for their navy's use.
"The transformation of Ream Naval Base is only to strengthen Cambodian naval forces' capabilities to uphold maritime territorial sovereignty and crack down on sea crimes," foreign ministry spokesman Zhao Lijian told reporters in Beijing Tuesday.
He added that Washington's criticisms were "malicious conjectures to attack and smear" Cambodia.
Concerns about the base go back as far as 2019, when the American newspaper the Wall Street Journal reported a secret draft deal allowing Beijing to dock warships there.
Cambodia has since dismantled facilities at the base that were built partly with American money and played host to US exercises.
