gotong-royong

Cooperation by members of a community to achieve a common goal.

These [Housing and Development Board housing estates] must be the core areas where the concept of neighbourliness and the friendly smile and greeting can and must be promoted and the kampung spirit of ‘gotong royong’ preserved. [Quoting an editorial in the National Youth Leadership Training Institute Alumni’s newsletter.]

An event where people clean up a place, such as sweeping and removing rubbish.
