Yonghui Superstores said late Wednesday that an arbitration ruling involving Dalian Yujin Trading, Wang Jianlin, Sun Xishuang and Dalian Yifang Group has officially taken effect.

The company said it had applied to a court for enforcement, and the court has accepted the case and formally opened enforcement proceedings.

The dispute involves 3.639 billion yuan (US$500 million) in unpaid remaining share transfer payments, as well as related penalties, legal fees and arbitration costs, according to the filing.

The arbitration ruling was issued by the Shanghai International Economic and Trade Arbitration Commission.

The case adds to mounting financial pressure surrounding Wanda-linked entities as some of the group's past investment and asset transactions continue to face repayment and restructuring challenges.
