BEIJING - China saw more public-private partnership (PPP) projects registered in February, according to official figures.

A total of 8,780 PPP projects had been registered in a national data bank as of end of February, up by 45 from the end of January, according to the China Public Private Partnerships Center.

These projects had a combined investment of 13.3 trillion yuan (about $2 trillion), up 88.5 billion yuan from a month earlier.

Of all the projects, 4,920 entered the implementation stage, with a combined investment of 7.5 trillion yuan.

Construction has started on 2,373 projects, with a total investment of 3.3 trillion yuan.

PPPs are a collaborative investment model between government and private companies.

Chinese authorities have explored funding infrastructure and public works through PPP models since late 2013, reducing local government debts and opening new opportunities for private capital.
