Working in China requires "extraordinary persistence," according to world-renowned architect Moshe Safdie.
"Building in China is the most challenging," the 76-year-old told CNBC's "Managing Asia" as part of the "Asia Builders" special series. "Apart from the size, it is also complex because you need to satisfy a shifting set of regulations."
Safdie, the architect behind many famous buildings including the U.S. Institute of Peace Headquarters, India's Khalsa Heritage Memorial and Singapore's Marina Bay Sands, is currently working on a vast waterfront project at the confluence of the mainland's Yangtze and Jialing Rivers.
"[China's] permitting system, building codes and the planning reviews are not what we're used to… I think by the time we're done, it will probably be [another] 6 to 7 years," he said.
