Yunnan Water Investment (HKG:6839) plans to seek shareholder approval for a guarantee mandate of up to 2 billion yuan for the company and its subsidiaries, according to a Friday Hong Kong bourse filing.

The proposed guarantees would support bank credit facilities and other financing arrangements for the group's onshore and offshore subsidiaries, as well as guarantees among subsidiaries.

The company said the mandate would give the group greater flexibility to secure financing. Shareholders will vote on the proposal at the annual general meeting on June 26, the filing said.

Shares of the water supply and waste treatment company were up nearly 5% in Monday afternoon trade.
