The Edge Media in Malaysia has reported using inside sources that Singapore and Malaysian governments have reached an agreement to defer the construction of the Singapore-Kuala Lumper HSR without any penalties for a period of 2 years. This agreement was not a provision in the existing HSR agreement and Singapore was by no means obliged to make such a concession but in the spirit of good neighbourliness, this deferment agreement was reached.
If Malaysia had scrapped the HSR, they were liable to pay up to RM500 million to Singapore. This new deferment agreement will run till 31 May 2020 and the HSR would be legally required to commence construction then.
The original media report on this 2 year deferment can be found here.
