Singapore, being a wealthy city, can always buy land from neighbouring countries such as Thailand or Malaysia. These countries are in need of money therefore if Singapore offer them a high price, they will consider to sell us their land. However, everything needs to be demolished and rebuilt if we successfully bought their land and this requires another sum of money. This method is easy to carry out as our neighbouring countries are very big and they would be willing to give out a small part of their land in exchange of money. Therefore, the successful rate is very high.
