His social media posts come at a time when Malaysia's Prime Minister Mahathir Mohamad said that Malaysia plans to renegotiate the 1962 Water Agreement with Singapore for it is "too costly", although he said a day later that it is "not an urgent matter".

S'pore supplied extra water to Johor during drought seasons

Under the 1962 Water Agreement, Singapore is entitled to draw up to 250 million gallons of water from the Johor River daily.

Johor is also entitled to a daily supply of treated water of up to 2 percent of the raw water it supplies to Singapore.

But in 2016, Johor's Sungai Loyang dam was hit incredibly hard by a dry spell and the Johor River was polluted as well, bringing potable water down to a short supply for Johoreans.

Singapore then increased its supply of treated water to Johor from 16 million gallons to 22 million gallons daily at Johor's request.

The Johor Crown Prince is not the only one with positive comments for Singapore.

Malaysia's Defence Minister Mohamad Sabu also said in an interview with The Straits Times published today (Jun 29) that although Singapore and Malaysia are like married couples whose relationship goes through problems from time to time, the two neighbours are adept at resolving them.
