This city is supposed to be the "diamond" on China's Silk Road Economic Belt - a new metropolis carved out of the mountains in the country's arid northwest.
But it is shaping up to be fool's gold, a ghost city in the making.
Lanzhou New Area, in Gansu province, embodies China's twin dreams of catapulting its poorer western regions into the economic mainstream through an orgy of infrastructure spending and cementing its place at the heart of Asia through a revival of the ancient Silk Road.
Hundreds of hills on the dry, sandy Loess Plateau were flattened by bulldozers to create the 815 sq km city. But today, cranes stand idle in planned industrial parks while newly built residential blocks loom empty. Streets are mostly deserted. Life-size replicas of the Parthenon and the Sphinx sit surrounded by wasteland, monuments to profligacy.
The project epitomises what is wrong with China's economic model, foreign experts say - in particular, how debt is rising to alarming levels as the Government tries to prop up a slowing economy with projects that make little or no commercial sense.
"Where Gansu goes, China goes," said Rodney Jones, founder of Wigram Capital Advisers in Beijing. "You've had massive credit growth and investment in projects that don't generate an economic return.
"Now you're facing two shocks - you've got to stop credit growing and deal with the bad loans, and you've also got to see how the economy expands once this credit boom is over."
China launched an ambitious "Go West" campaign at the turn of the millennium, aiming to narrow the income gap between the booming eastern seaboard and the remote west, essentially by building modern infrastructure and exploiting the west's natural resources.
The initiative got a huge boost as China launched a nationwide economic stimulus after the 2008 global financial crisis. And President Xi Jinping's plans to revitalise the Silk Road, the ancient desert trade route between East and West, have provided a further boost.
About US$10 billion is being invested to clear Lanzhou New Area and build infrastructure that includes roads, railways and an expanded airport. Water is being diverted from a branch of the Yellow River and stored in three new reservoirs to create a city that a promotional video shows as awash with lakes and rivers.
A free-trade zone and logistics hub are meant to ensure that the city benefits from its location on a new Silk Road, while industrial parks dedicated to auto and equipment manufacturing, petrochemicals and traditional Chinese medicine are supposed to create the jobs that will sustain a city of one million by 2030.
On a recent trip organised by the provincial government, journalists were shown around a heavy-machinery plant run by the state-owned Lanzhou LS Group and the privately owned Scisky factory, which makes a water-based polymer resin. Scisky executives said they hoped to take advantage of local raw materials and export to Central Asia and Europe.
Xu Dawu, deputy Communist Party secretary for the New Area, says 150,000 people live here, with 40,000 temporary construction workers - but those numbers seem at odds with the largely empty vistas that visitors see.
The reality is that despite cheap land, tax holidays and large subsidies, the New Area has struggled to attract both investment and people. Yan Yuejin at E-house China R&D Institute in Shanghai looked at vacancy rates and concluded that the venture has been "very unsuccessful".
Even Xu admits to "a problem".
"Lanzhou is a very important town on the Silk Road, but it is sandwiched between two mountains with a river running through it," he said. To draw more industries from the south, he said, "we need to jump out of Lanzhou and seek a larger space."
If that doesn't work, he said in what sounded like a tacit admission of defeat, "we can at least develop modern agriculture here".
Chinese economists said Gansu is making basic economic missteps, investing in heavy industry at a time of global overcapacity and building infrastructure when it should be reducing its debt.
"This is just copying the old development model without taking local reality into consideration," said Ding Wenfeng, a professor of economics at the Chinese Academy of Governance, urging the Government to apply an "emergency brake."
"Urbanisation and modernisation are processes that naturally take place," he said. "You can't force it to happen or have 1000 places copy the same model."
Bao Cunkuan, an environmental science professor at Shanghai's Fudan University, agreed, arguing that the poorer northwestern provinces such as Gansu have typically survived by exporting people to richer parts of China, not by attracting people.
"People will vote with their feet," he said. "If the place is not good enough, nobody will come no matter how many houses you build. Where people go, the allocation of capital and resources should follow."
Gansu has a per capita annual income of just US$4000 and little trade with the outside world. Its growth was driven by metals and other minerals, as well as by real estate, but it is suffering the ill effects of China's slowdown and a global slump in commodity prices.
The province's attempt to spend its way to prosperity has only aggravated its problems. Last year, total credit expanded by about US$50 billion, in an economy worth just US$100 billion, Wigram Capital calculates. Despite the huge injection of credit, the economy shrank 1 per cent in nominal terms, while the ratio of loans to gross domestic product expanded to 200 per cent, up from under 90 per cent in 2009.
Andrew Polk at Medley Global Advisers in Beijing visited Lanzhou New Area recently and noted its "desolate" location. "You can just sense from being there it's not a commercially viable place," he said.
Yet the eagerness to support Xi's hallmark Silk Road initiative - an economic belt running through Central Asia to Europe and a maritime Silk Road hugging Asia's southern coastline - seems to trump economic sense.
"It's just another example of government priorities being at odds with each other," Polk said. "There is a desire to do the belt and road programme, and there is also a desire to de-leverage. You can't do both at the same time, but we have seen time and time again in China which tends to win out."
Indeed, Gansu is far from an isolated case. The idea of building new cities around China caught on after the success of Pudong in the 1990s, as skyscrapers replaced farmland on the east bank of the Huangpu River facing old Shanghai.
But Shanghai's success remains an exception.
"Everyone wanted to build new cities - they thought they could replicate Pudong all over China," said Jones of Wigram Capital. "Provinces didn't have a strategy built around their comparative advantages. Building a new city in Gansu just doesn't make any sense."
There are other problems with a project on the scale of Lanzhou New Area. Writing in Nature magazine in 2014, three Chinese scientists warned that the environmental impacts of this and similar "mountain-moving" undertakings had not been properly considered, likening them to "major surgery on the Earth's crust".
The Lanzhou project was halted in 2013 because of problems with air pollution, pending an environmental assessment, Peiyue Li, Hui Qian and Jianhua Wu wrote. Four weeks later, as contractors' costs mounted, it was restarted - without the assessment.
Gao Ying, of the Shanghai Academy of Environmental Sciences, told China Business News in November that petrochemical plants planned for the new city could cause serious environmental and air pollution, as well as using vast amounts of water in a fragile and arid zone.
In China, debt has ballooned to 280 per cent of gross domestic product, from 135 per cent in 2009, Wigram Capital calculates. Bad loans are soaring and new debt is increasingly being used to pay back old loans.
It now takes 4 yuan of debt to generate 1 yuan of economic growth, up from 1 to 1 at the time of the financial crisis.
The Economist magazine warned this month of China's "coming debt bust," arguing that these trends were unsustainable and recommending that the Government plan for "turmoil".
The central Government talks of reducing industrial overcapacity, cutting debt and transitioning to a new, innovation-driven economy, but provincial leaders, under pressure to meet economic targets, seem unable to abandon the old playbook.
"You can see why they keep returning to the well, because it did work for a long time - it was extremely successful," Polk said. "That's the core of the issue right now. People are grappling with the changing nature of the economy. Old tricks don't work."
The old tricks could even be making matters worse: Fudan University's Bao compares the approach to "drinking poison when you are thirsty".
