Hong Kong (CNN) - Spanning more than 68 countries and encompassing 4.4 billion people and up to 40% of the global GDP, China's One Belt, One Road project is not short on ambition.
Its boosters tout its massive economic promise and claim it could benefit the entire world and lift millions out of poverty.
But no one can say for sure what exactly the plan encompasses, and detractors warn it could be an expensive boondoggle at best or a massive expansion of Chinese imperial power at worst.
So what is One Belt, One Road?
No one is totally sure. At the most basic level, One Belt, One Road (OBOR) is a collection of interlinking trade deals and infrastructure projects throughout Eurasia and the Pacific, but the definition of what exactly qualifies as an OBOR project or which countries are even involved in the initiative is incredibly fuzzy.
Why is it so unclear?
While it might have originally had a comprehensible thesis behind it, OBOR has become such a popular buzzword that it's next to impossible to lock down criteria for how any given project would or could fit into the overall initiative.
Chinese officials tend to mention it regardless of what they're trying to promote, like a US lawmaker talking about "freedom."
What does China get out of this?
According to Chinese state media, some $1 trillion has already been invested in OBOR, with another several trillion due to be invested over the next decade.
"China is looking to use OBOR as a way to ship its own domestic overproduction offshore," said Nick Marro, an analyst with the Economist Intelligence Unit (EIU).
"(China is) leveraging their own capital to get involved in helping (other) countries to get wealthier so they can become customers of Chinese products," he said.
What are the economic risks?
Balding said China "has a very poor track record of their investment overseas," pointing to widespread problems with Chinese projects in Venezuela, Sri Lanka and Myanmar.
What are the political benefits?
Most analysts agree that, for all its rhetoric about trade and development, OBOR is primarily a political project.
"China's new 'empire' will be an informal and largely economic one, posited on cash and held together by hard infrastructure," Miller writes.
What are the political risks?
If successful, OBOR could see China supplant the US as the main superpower in much of the world -- but Xu warned the project could also backfire considerably because of its size.
