Australia will launch a seven-nation Indian Ocean military exercise next week, starting in Sri Lanka where China has invested in strategic ports and loaned huge amounts to build other infrastructure, Canberra's envoy said Friday.
Some 1,000 Australian security personnel in four naval ships and a military aircraft will participate in the biggest joint exercise yet with their Sri Lankan counterparts, Canberra's top envoy in Colombo, Jon Philp, said.
"Sri Lanka and Australia are increasingly like-minded on maritime security and Indian Ocean issues," Philp said adding that the two countries will improve cooperation and familiarity with each other's defence forces.
Australian forces will move to neighbouring India on March 26 and thereafter travel to Malaysia, Thailand, Vietnam, Indonesia and Singapore before returning to Darwin after two and a half months.
The joint exercise comes as concerns grow over Beijing's influence on Sri Lanka's economy and Chinese control over two key ports.
Unable to service a $1.4 billion Chinese loan to build a deep-sea port in the island's south, Colombo leased the facility to a Beijing company for $1.12 billion in 2017.
A state-owned Chinese company also runs Sri Lanka's biggest container terminal in Colombo.
Neighbouring India as well as Western nations have expressed concern about China's foothold on vital locations in Sri Lanka which is strategically placed along the most important East-West sea route.
An ambitious plan, seeking to link Asia, Europe and Africa with a network of ports, highways and railways, has seen China disperse tens of billions of dollars in loans to developing nations, sparking fears of a "debt trap".
The largest single lender to Sri Lanka, China has secured contracts to build roads, railways and ports.
Philp played down China's growing presence in the Indian Ocean region saying Canberra considered Beijing a "extremely important" partner.
"We welcome China's role in the region and look forward to working with China," he said.
Growing fears of political influence from foreign states, particularly China, saw Australia pass a raft of new laws last year to curb potential meddling.
