SYDNEY — Australian officials confirmed Monday that their country will not be used as a base for any planned U.S. mid-range missiles following talks with American officials in Sydney.

U.S. Defense Secretary Mark Esper said at last weekend’s meetings that he wanted to deploy intermediate range conventional missiles at various Asia-Pacific sites within months.

The move follows the Trump administration’s withdrawal from a Cold War-era arms control treaty with Russia. It also comes in the wake of Chinese military expansion in the Asia-Pacific, and is likely to anger Beijing.

Esper: US to soon put intermediate range missile in Asia U.S. Defense Secretary Mark Esper said he wants to deploy an intermediate range conventional missile in the Pacific region within months, now that the Trump administration has formally pulled out of a Cold War-era arms control treaty with Russia.

Australian Defense Minister Linda Reynolds said Monday that while the locations for the missile bases were not yet known, Australia would not be one of them. She said Esper made no such request, and no such request was expected from the U.S.

“I asked him directly, ‘Was there any expectation of a request,’ and he said, ‘No,’” Reynolds told Australian Broadcasting Corp. radio.

Prime Minister Scott Morrison later echoed Reynolds’ comments that the missiles would not be based in Australia.

“It’s not been asked of us, not being considered, not been put to us. I think I can rule a line under that,” Morrison told reporters in Brisbane on Monday.

Prior to the talks, Esper said he intended to deploy intermediate range missiles in locations throughout the Asia-Pacific region. Such missiles are capable of flying about 1,000 kilometers (620 miles).

The step comes after the Intermediate-range Nuclear Forces treaty — signed between the U.S. and Russia in 1987 — expired last Friday. The U.S. says it plans to begin testing new missiles that would have been prohibited under the accord.

“We now are free to develop that range of weapons, 500 kilometers to 5,500 kilometers, that had not been available to us from a ground-based deterrent posture,” Esper told reporters before the weekend meetings.

Pentagon plans tests of long-banned types of missiles The Pentagon plans to begin flight tests this year of two types of missiles that have been banned for more than 30 years by a treaty from which both the United States and Russia are expected to withdraw in August, defense officials said Wednesday.

U.S. missile ambitions in the region raise the possibility of an arms race with China, which would leave Australia in a difficult position between its most important security ally and its largest trading partner.

During the weekend meetings, Esper accused China of a “disturbing pattern of aggressive behavior” and “destabilizing behavior” in the region.

China hit back at what it called these “groundless attacks and slanders” in a statement from its embassy in Canberra.

Meanwhile, Morrison also indicated Australia could join a United States-led international effort to protect shipping in the Persian Gulf, stressing the importance of making the important trade route safer.

“It’s important that we make the Straits of Hormuz safer than they currently are,” he told reporters. "The purpose here is to de-escalate tensions, not to escalate them, and that has very much been the focus of the conversations we’ve had with our American partners.
