On June 25, 2018, Malaysian Prime Minister Mahathir Mohamed announced his intention to renegotiate the agreement with Singapore, as the low price at which water is exported to Singapore has caused Malaysia to lose considerable revenue.  Malaysia cannot unilaterally revise the price of water. Our legal situation remains unchanged. Measures must now be taken and taken to protect the Johor River from pollution and increase river performance and manage the total amount of water taken from the river. Singapore and Malaysia could otherwise find themselves in a very difficult situation on the road, especially in dry weather, and if you think that climate change will make the situation worse. In short, in 1998, Singapore and Malaysia began negotiations for a „framework for broader cooperation.“ During the 1998 financial crisis, Malaysia sought financial loans to support its currency; Singapore offered Malaysia to give its assurance of ensuring Singapore`s long-term water supply. In the end, Malaysia did not need the loans. The negotiations focused on other issues of common interest. In particular, Malaysia wanted to jointly develop other plots in Singapore in exchange for the transfer of its station away from Tanjong Pagar. On August 31, 2011, the 2011 water contract expired and the hydropower plants and facilities were handed over to the Johor State Government. The shed included the skudai and Gunung Pulai water treatment facilities, built by the Public Utilities Board and managed by them for 50 years, as well as two pump houses in Pontian and Tebrau.  PUB and its counterpart in Johor, Badan Kawalselia Air Johor (BAKAJ), have a close relationship.
PUB and BAKAJ meet regularly and conduct useful discussions on current weather trends, water levels at various dams and dams in Johor and plans for the development of water resources. PUB and BAKAJ are also working closely together on the Johor River Dam project. The Johor River Dam, in operation since August 2016, helps prevent the use of saline and improves the reliability of the Johor River water supply, benefiting Singapore and Johor. While discussions on the code of conduct are expected to conclude in 2021, Saifuddin said he saw some countries oppose the legality and application of the code. A legally binding code „would be the most difficult part,“ he said. „I can predict that there may be some difficulties in trying to repair the details. Nevertheless, I am very confident that we will reach an agreement. I explained all this in detail so that Malaysians and Singaporeans understand that we are taking a coherent, constructive and mutually beneficial approach to the development of water infrastructure in Johor.
