SYDNEY — Australia’s government backed its ambassador to Washington, former Prime Minister Kevin Rudd, after U.S. presidential contender Donald Trump called the key diplomat “a little bit nasty” in a broadcast interview.

Australia counts the U.S. as a major strategic ally and the two are forging closer defense ties under the AUKUS pact to build nuclear submarines in Australia.

Trump described Rudd as “a little bit nasty” in an interview with former British politician Nigel Farage on British broadcaster GB News.

“If he’s at all hostile, he will not be there long,” Trump added.

Rudd, a former China scholar who was chief executive at U.S. think tank the Asia Society before becoming ambassador, has previously criticized Trump, on China policy, among other issues.

On Wednesday, Foreign Minister Penny Wong told reporters Rudd would stay as ambassador even if Trump were elected president.

“Mr. Rudd is a very effective ambassador,” she said in Canberra, the Australian capital. “He is recognized across this Parliament as doing an excellent job in advancing Australia’s interests in the United States.”

She pointed to Rudd’s work on the AUKUS pact, adding that he had engaged with members of the U.S. Congress on both sides of the aisle.

The Trump comments inspired an attack on Rudd by the opposition, which asked in Parliament whether his role would be re-assessed.

In reply, Prime Minister Anthony Albanese said he had never before seen an attempt to politicize Australia’s representative overseas, adding that the leader of the opposition had welcomed Rudd’s appointment at the time it was made.
