This story is part of an ongoing series on US-China relations produced jointly by the South China Morning Post and POLITICO , with reporting from Asia and the United States. A top Chinese general has a warning for any US leaders planning an arms race in space: be prepared to lose. Outspending a rival power into economic exhaustion might have helped the US win the cold war, said Qiao Liang, a major general in the Chinese air force who co-wrote the book Unrestricted Warfare: China’s Master Plan to Destroy America . But he said it would not work against a wealthy manufacturing powerhouse like China. “China is not the Soviet Union,” Qiao said in an interview with the South China Morning Post , a news partner of POLITICO . “If the United States thinks it can also drag China into an arms race and take down China as it did with the Soviets … in the end, probably it would not be China who is down on the ground.” Qiao’s words come as both Washington and Beijing are pouring money and resources into an increasingly militarised space race that some security specialists and former US officials fear is heightening the risk of war. The aggressive manoeuvres include US President Donald Trump’s proposal for a stand-alone Space Force – which Qiao dismissed as “an unwise move” – and efforts by both countries to develop laser and cyber weapons that could take out each other’s satellites. The rivalry is plainly on the minds of leaders at the Pentagon, which cites “space” 86 times in a new threat assessment of China’s military. It also warns that the People’s Liberation Army (PLA) is working on “enabling long-range precision strikes” and developing directed-energy weapons for use in orbit. Sea launch rockets China to forefront of global space race Trump, Vice-President Mike Pence and a slew of US military leaders have cited China’s military space programmes as a key rationale for proposing the Space Force, which would gather nearly all the defence department’s space-related programmes into a new military branch – similar to the one China created four years ago. Congress is considering the administration’s plan, although some defence hawks are sceptical. Pence has also expressed alarm at China’s success in landing uncrewed probes on the moon , a place US astronauts last visited in 1972. “Last December, China became the first nation to land on the far side of the moon and revealed their ambition to seize the lunar strategic high ground and become the world’s pre-eminent spacefaring nation,” Pence said at a meeting of the National Space Council in March. Even more worrying, neither country seems interested in placing the issue on the diplomatic agenda to lower the tensions, some security advocates say. That is in contrast to the decades of space cooperation that have existed between the US and Russia. “One of my biggest concerns is that for all the talk about how horrible an armed conflict with China would be for everyone, all the current US policies and actions seem to be preparing for armed conflict instead of avoiding it,” said Brian Weeden, director of programme planning at the Secure World Foundation, which advocates for using space in a peaceful and sustainable way. “There is not a lot of dialogue between the US and China,” he said. But other space experts say China is a greater threat to the United States than most people realise – and even an “imminent threat”, according to independent analyst Namrata Goswami. “If anything, it [the threat from China] is underappreciated and underplayed in the US,” she said. “I suspect that is because the US military might not want to call attention to its own vulnerabilities regarding its space assets.” Chang’e 4 lunar probe sends first photo of far side of the moon Qiao said China was not seeking a space war but was preparing to counter any nation, including the US, that sought to pose a threat to its national security. China’s economic prowess left it well positioned to prevail in an expensive contest with the US, he said. “When the United States and the Soviet Union engaged in the cold war and the arms race, the United States was the largest manufacturing country, and the Soviet Union was not even the second,” he said. “But today it is China who is the world’s top manufacturer.” Recent reports from US spy agencies and think tanks indicate that China’s efforts are advancing quickly. Those include estimates that China will soon be able to field high-powered lasers designed to attack objects in low-Earth orbit – and evidence that its weapons can already attack targets much further from the Earth than the United States can. China’s reliance on space assets is also expanding: it has more than 120 intelligence, surveillance and reconnaissance satellites of its own – second only to the United States. About half of them are owned and operated by the military and could be used to track and target US forces around the world, the report warns. Will China’s new laser satellite be ‘Death Star’ for submarines? The threat getting the most attention is the danger China’s orbiting weapons might pose to the satellites the United States relies on for communications, navigation and surveillance – for both military operations and economic well-being. China is heavily investing in so-called counterspace technology, including the development of at least three antisatellite missile systems, according to an April report from the Centre for Strategic and International Studies. It is also developing satellites that can make physical contact with other satellites in orbit, the report said. While that technology can be used for repairs in orbit, it can also be used to disable a satellite or tear off a solar array to impact a satellite’s power source. The Pentagon’s “China Military Power” report found that China is also pursuing new jamming and “directed energy” weapons that can interfere with satellites. In a conflict, that technology would probably be used to “blind and deafen the enemy”, the report said. China also reorganised the PLA in 2015 to create a Strategic Support Force, a military branch dedicated entirely to space, electronic and cyberwarfare. The new branch was designed to bring space assets from across the military under one organisation, similar to the goal of the US Space Force. The space-centric branch, which reports directly to the Central Military Commission, is focused primarily on satellite launches and intelligence, navigation and communication operations, but also conducts research and development on new counterspace capabilities, according to the US Defence Intelligence Agency report published in February. China ‘has overtaken Russia’ as a maritime power Chinese military units are also training with missiles that could damage or destroy satellites, the agency also reported in February, adding that China will probably have a ground-based laser that can blind optical sensors on satellites in low-Earth orbit by 2020. Unlike the United States or Russia, China is also believed to have the capacity to use missiles to attack satellites in the more distant geosynchronous orbit, or 35,000km (22,000 miles) above Earth. If any country were to launch a physical strike in geosynchronous orbit (GEO), the debris field would make the area, which is today used for critical missions like early missile warning and weather observations, unusable. “We have much more to lose in GEO than any other country,” said Kaitlyn Johnson, an associate fellow who specialises in space security at the Centre for Strategic and International Studies. “We wouldn’t want to have a first strike capability.” Military experts also worry that China could try to seize areas of the moon that contain strategic resources including ice that could be used for rocket fuel or life support. But they say it is much more likely China will want to use dominance in space to influence conflicts on Earth. For instance, being able to threaten the military’s GPS or communications satellites might deter the US from getting involved in a conflict in the South China Sea, Weeden said. The US Space Force is intended to close some of those gaps by grouping space assets together to build expertise and giving the new service autonomy over its budget requests. One of the biggest goals of the new branch is to speed up space acquisitions, allowing new technology to be fielded faster, and to develop a space “doctrine” that would oversee how the US fights conflicts when space platforms are at stake. China adds new satellite to rival US global positioning system The Chinese government insists that it is merely responding to aggressive US moves to dominate space militarily. Qiao called it “bullying and hegemonic” for the United States to insist that other countries cannot follow suit. “The US space troops have long existed,” he said. “They just did not become an independent force … moreover, the US possessed anti-satellite capabilities as early as the 1970s and 1980s. China only developed anti-satellite capabilities at the end of the 1990s and even in the first decade of this century.” China had little choice but to enhance its capabilities, he said. “China’s purpose to develop space capabilities, firstly, is we do not want to be blackmailed by others,” Qiao said in the interview. “Second, we hope to use space peacefully. But if others want to oppress us by occupying the heights of space and opening up a ‘fourth battlefield’, China will certainly not accept it.” Still, China remained far from surpassing US dominance, he said. “We cannot overtake the US in the next decade or two, but we will narrow the gap in a comprehensive way. And it is possible we may take the lead in some individual areas.” Weeden agreed. “China is developing many of the same space capabilities the US did decades ago, while the US is focused on sustaining its capabilities and making them more resilient,” he said. “On the whole, the US is still far more capable than China is but the relative advantage is narrowing.” What is space junk and why is it a problem? The two nations have some diplomatic channels through which they could cooperate in space, including the United Nations’ Committee on the Peaceful Uses of Outer Space, of which both are members. In 2015, the Obama administration established a dialogue with China on space safety, which is quietly continuing under Trump, although Weeden said the meetings were mostly high-level talks. But the Wolf Amendment, which was first passed in a Congressional appropriations bill in 2011, forbids the US government from working with China and prohibits any bilateral cooperation between the China National Space Administration and the US National Aeronautics and Space Administration on national security grounds. And there is virtually no collaboration between the militaries of the two nations today. To open the door for conversations that could ease tensions and avoid miscommunication, the US and China must “crawl before we walk”, Audrey Schaffer, the director of space strategy and plans at the defence department, said at a March event on US-China space relations hosted by the Secure World Foundation. Some potential first steps include the two countries sharing information like their national defence strategies, providing launch notifications of space vehicles or opening routine, secure communications channels between diplomats. Each step would help build trust and transparency, Schaffer said, pointing to the strong relationship between the US and Russia in space as evidence that it could be done. “Even then when the relationship was just as strained, if not more so, we did manage to work bilaterally and multilaterally with the Soviets to really create mechanisms that would help reduce the risks of conflict and enhance stability,” Schaffer said.
