That is the view of analysts who warn increasingly aggressive maneuvers by Chinese fighter jets -- accused of endangering both Canadian and Australian aircraft and crew in recent incidents -- are a sign Beijing is pushing its territorial claims to a dangerous new level.
And it is the threat of this brinksmanship spiraling into a conflict -- possibly following the downing of a warplane -- that will be exercising minds when Asia's biggest defense summit, the Shangri-La Dialogue, begins in Singapore on Friday.
All eyes will be on US Defense Secretary Lloyd Austin and his Chinese counterpart, Wei Fenghe, both of whom will address the conference on their visions for security in the region and are expected to meet each other on Friday evening for bilateral talks.
Senior US defense officials said that Washington will focus in part on "setting guard rails on the relationship," one official said, while calling for more mature crisis communications mechanisms to ensure that the growing competition between the world's two preeminent world powers does not escalate into conflict.
"One of the ground rules that we aim to establish with the PRC is that we're going to characterize our position and they can characterize their position," the official said. "I think we are taking every effort to ensure that this is a professional, substantive meeting."
Analysts will be watching for an insight into why China has dialed up its aggression -- and whether this represents a new front in what many are already referring to as a "gray zone" conflict.
Peter Layton, a fellow at Australia's Griffith Asia Institute, is among the many who say China's recent actions are a "dangerous" escalation in such tactics.
In his words, "It's time to be alarmed, not just alert."
The Gray Zone
Gray zone actions are military-speak for coercive actions, aimed at achieving national political objectives, that fall short of actual war.
Many analysts use the term to describe Beijing's actions in the South China Sea. China has spent years turning remote islands and obscure reefs in disputed areas of the sea into fortified military bases and airstrips and it has also been accused of using fishing vessels to swarm territory it claims as its own. China continues to claim the vast majority of the 1.3 million square mile sea, where it has territorial disputes with various other countries, despite a landmark international tribunal that ruled against its claims in 2016.
Layton, writing on the Lowy Institute's blog, said China is now "pushing the envelope" on its gray zone tactics with its "increasingly aggressive" intercepts of airplanes belonging to US allies.
In May, a Chinese J-16 fighter jet is alleged to have cut across and released "chaff"
-- tiny strips of aluminum used to decoy radar-guided missiles that can be harmful to a pursuing aircraft if ingested into an engine -- into the path of an Australian P-8 reconnaissance jet near the South China Sea. That incident, blasted as "very dangerous" by Canberra, which said the chaff had been ingested into the P-8's engine, followed similar claims by Canada that on several occasions Chinese jets had buzzed its reconnaissance craft
operating out of Japan, endangering Canadian airmen.
While those incidents have alarmed the US and its allies, Beijing insists foreign nations are to blame and has reacted angrily to both Australia and Canada.
Take this response by Chinese Defense Ministry spokesman Tan Kefei to Canberra:
"With the Australian aircraft seriously threatening China's sovereignty and security, the Chinese military responded with professional, safe, reasonable and legal measures. The Australian side has since confused right and wrong, and repeatedly spread misinformation to advocate and create confrontation."
Layton and others aren't buying that -- they say China is following a very deliberate game plan.
Targeting weak links, but why now?
Beijing is using its pilots in a high-stakes "game of chicken," said Oriana Skylar Mastro, an expert on the Chinese military and a non-resident fellow at the American Enterprise Institute.
It's a game Beijing believes it will win because it isn't worried about the possibility of escalation, but knows Western countries are, Mastro said, adding that the "Chinese don't believe in inadvertent escalation."
"If there's a crash, the Chinese either want to fight a war and they will or they don't and they won't," she said. "From their viewpoint, it doesn't make any sense you would be pushed into a war you don't want to fight."
"They are engaging in these risky behaviors and then saying (to opponents), it would be safer for you if you weren't here."
If that's the case, why now?
Mastro and others said it is significant that China has so far picked US allies -- rather than the US itself -- for this game of chicken.
Doing so could be its way of trying to fracture a US-assembled coalition of Pacific partners, said Timothy Heath, senior international defense researcher at the RAND Corp. think tank.
He noted the increased importance Washington is placing on the Quad
-- its informal alliance with Australia, India and Japan
that has held two summits in the past year -- and US statements about building coalitions to stand by Taiwan
, the democratically self-ruled island Beijing considers part of its territory and has threatened to take by force if necessary.
"Targeting US allies like Canada and Australia could be a way to probe weaknesses in such coalitions and raise awareness in the h
