Many Hong Kong-listed Chinese developers have faced winding-up petitions since the sector slipped into a debt crisis in mid-2021. Many property firms have defaulted and are undergoing debt restructuring.

Kaisa said the petition was filed by Broad Peak Investment Pte Advisers Ltd at the Hong Kong High Court on July 6, and the issuer of the yuan bonds is its wholly-owned subsidiary, Kaisa Group (Shenzhen) Co Ltd.

The Shenzhen-based company said it would seek legal measures to oppose the petition vigorously, and it would continue to proactively communicate with its offshore creditors on the restructuring plan, with the objective of announcing terms to the market as soon as practicable.

The first hearing for the petition will be on Sept. 13.
