US, China agree to Asia defence rules on air crashes

The document urges warplanes to establish communication with other aircraft and avoid signals that are provoking

SINGAPORE • Defence chiefs from the US and China agreed in principle to guidelines on encounters between warplanes, in the latest bid by Pacific nations to keep increased military activity from escalating into conflict.

US Secretary of Defence James Mattis and seven other regional military chiefs, including China’s General Wei Fenghe, gave broad endorsement to the rules in Singapore on Saturday, during a meeting hosted by Asean. The non-binding guidelines had been formally adopted a day earlier by defence ministers from Asean’s 10 member nations.

The document, which follows similar guidelines on naval encounters signed in 2014, urges military planes to establish communication with other aircraft, identify themselves and avoid manoeuvres or signals that could provoke a response.

“These guidelines will help reduce the likelihood of encounters or incidents spiraling into conflict in the event of a miscalculation,” it said.

The 18-member Asean-Plus Eight Partners also include Australia, India, Japan, New Zealand, Russia and South Korea. The full grouping could formally adopt the air-encounter guidelines during next year’s Asean meetings in Thailand.

Growing Competition
The rules represent the latest attempt to manage a surge in military activity in the Western Pacific as China’s extends its naval and air reach.

The US — the region’s dominant security power since World War II — has stepped up its presence to assert free navigation rights in the South China Sea and other waters claimed by Beijing.

“Once a mishap occurs, there’s a dynamic that ensues that you cannot control,” Singaporean Defence Minister Ng Eng Hen, who led the meetings, told reporters on Saturday.

“We recognise that the price of any physical incident is one that is too high and unnecessary to either assert or prove your position.”

Mattis has sought to play down military disputes with China during the trip, which included a 90-minute meeting last Friday with Wei. While Wei reaffirmed Chinese concerns about the South China Sea and Taiwan, the two sides agreed to deepen trust and let military ties play a stabilising role in the relationship, according to the country’s Defence Ministry.

The US and China have in recent years complained of tense midair encounters, with each side accusing the other of endangering its aircraft and personnel. The US has also accused China of target ing its pilots with lasers, something specifically discouraged by the Asean guidelines.

The rules seek to build on the 2014 agreement signed by 21 nations on naval protocols, known as the Code of Unplanned Encounters at Sea, or CUES.
