One of China's less publicized avenues for pumping funding into the country's struggling property market is running into the same problem that's long plagued the industry: supply is overwhelming demand. The market for publicly listed REITs, introduced in 2021, is showing signs of fatigue, with a glut of deals in the pipeline more than $13 billion worth of offerings - set to add to the supply, including two that will begin raising funds next week. That deluge threatens to undermine a market that has grown to $33 billion as Beijing seeks to tap its massive capital markets to fund real estate projects and ease the burden on local governments.
