The tension is evident in many countries with deep economic ties to the US, including South Korea, Japan and Germany. But perhaps nowhere is the tug more vivid than in Australia, long one of America's closest allies, which now finds itself pulled in the opposite direction by China, its largest export market.
In elections scheduled for Saturday, both major parties have called for a balanced foreign policy, aimed at maintaining the country's long-standing national security alliance with the US — while also looking to nurture the relationship with China.
Neither party's leaders have adopted the bellicose anti-China language of US President Donald Trump, nor the use of tariffs to try to force the Chinese to yield to Australian demands.
The Trump Administration recently raised tariffs on US$200 billion of Chinese imports to 25 per cent from 10 per cent and threatened to expand the tariffs to encompass all Chinese imports.
Australia's cultural affinity with the US remains strong. Australian and US troops fought together in World War II, and more recently in Afghanistan and Iraq. The countries' intelligence agencies share some of their deepest secrets.
But in terms of cold hard (Australian) dollars, the nation's business and political leaders now speak of the world's two largest economies as equally important partners.
"Our interests are not identical to the US," Geoff Raby, a former Australian ambassador to China who advises companies doing business in the two countries, said in an interview.
"That doesn't mean we can't have a close, warm relationship with the US. But we cannot join the US in a policy premised on China being a strategic competitor."
Australia is essentially trying to navigate the world economy as a midsize country maintaining good relations with both superpowers.
It is trusting the US as an ally on national security matters but also knows that its economic future, and present, are tied to China. Australia and China have had a trade agreement since 2015.
China's huge population and rapid growth will inevitably pull more countries into its economic orbit. But that strong pull also reflects recent steps by the US to undermine institutions that Americans themselves helped create to guide the global economic system.
The Trump Administration, for example, has levied steel and aluminum tariffs on close allies, ostensibly on national security grounds; walked away from the Trans-Pacific Partnership, aimed at creating a trade bloc that could counter Chinese influence; and taken steps to undermine the World Trade Organisation, which many smaller countries view as essential to getting a fair shake in global commerce.
The incumbent Government, led by Prime Minister Scott Morrison, has sought to maintain close ties with both the US and China. It has passed a law to try to reduce foreign influence in Australian politics and is pledging increases in spending for defence and cybersecurity.
"Inevitably, in the period ahead, we will be navigating a higher degree of US-China strategic competition," Morrison said in a major foreign policy speech late last year.
Leaders of the Australian Labor Party, aiming to take power for the first time since 2013, are less friendly to the Trump Administration; they embrace economic ties to China while appearing reluctant to be pulled too close in either direction.
"Differences between our systems and values will inevitably affect the nature of our interactions," Penny Wong, a senator expected to be foreign minister if Labor prevails, said in a recent appearance. "But those realities include the fact that China will remain important to Australia's prosperity."
The absence of a full-throated debate reflects a widespread acceptance that the economic relationship with China is too important to mess up.
"The silence during the campaign is almost eerie," said Richard McGregor, a senior fellow at the Lowy Institute, a think-tank in Sydney. "Neither party sees any overwhelmingly partisan advantage in taking the issue on. And both parties know that they could make life harder for themselves with China later because of things said in the heat of the battle."
A look at the structure of the Australian economy shows why. The most economically consequential exports are commodities, including iron ore, coal and natural gas, which have helped provide raw materials for China's economic surge over the past three decades. But these natural resource industries are only part of the picture.
There are about 165,000 Chinese-born students in Australian universities, a crucial revenue source.
Buyers from China helped fuel the housing market, at least until recently; tighter restrictions on Chinese citizens' freedom to move money abroad have been a factor in the sector's downturn.
The Australian wine industry was once almost entirely focused on domestic production, then expanded to exporting to Britain and then the US. But in the past 10 years, three forces have combined to make China the largest export market for Australian wine.
The ranks of the Chinese middle class have grown astronomically. The 2015 trade agreement between the two countries reduced tariffs. And an extensive marketing campaign has helped ensure that many Chinese consumers would favour Australian labels.
Tony Battaglene, chief executive of Australian Grape and Wine, the industry's trade group, said: "We don't want either party to see us taking sides with the other party. It's delicate political ground, and we don't want to get caught up in the wash."
In 1994, Catherine Cervasio started a company, Aromababy, that makes organic skin care products in Melbourne. She soon began exporting to Hong Kong and Singapore, and since 2008 has exported to the Chinese mainland, which accounts for about half the company's revenue.
The company is not yet exporting to the US, although she hopes to develop a US business eventually. "It's a lot further geographically," Cervasio said. She visited China seven times last year and has taken lessons in the language.
"There is more synergy among Asian markets and Australia," she said, especially around personal care products.
In effect, the combination of population and geography made an Australian shift into the Chinese economic orbit inevitable once China began opening its economy in the 1980s.
What has changed in the past couple of years is that the risk of a bifurcating world trade system has created new urgency in trying to keep options on both sides.
"There's no need for Australian business or the Australian Government to be hard and fast about allying with either China or the US to the exclusion of the other," said Adrian Perkins, a partner at the law firm King & Wood Mallesons, the merged product of Chinese and Australian firms. "The sensible path is to keep all options open. We needn't shut them down."
What is sensible for Australia's economy and geopolitics means that what was once a special relationship with the United States is no longer quite so special.
