TNR is still a developing method of controlling feral cat populations. In some countries there is a blurring of the demarcation between domestic, stray and feral cats. The feral cat is accepted in some countries. TNR is therefore not considered because the need to control feral cat populations is not considered. These countries have not developed to the point where TNR is referred to.
Also in cooler European countries the feral cat is hardly visible (England, Germany). Therefore there is not a pressing need to control the feral cat population. However, it would seem that the old, developed countries have developed TNR more. This is to be expected. I refer to European countries. Holland has an excellent approach for example. And some of the earliest TNR program studies come from England.
There is a tug of war on the efficacy of TNR in some younger developed countries. The argument swings between killing and more humane techniques. North America falls into that bracket I believe but tends to decide upon TNR as the preferred method. Conversely Australia tends to favour killing in this battle between humane and cruel controls. I would expect the USA and Australia to come around to the TNR way of thinking in due course. Israel falls into the middle ground as well.
Japan and Hong Kong have barely got of the ground on developing TNR. However Japan has good animal welfare laws.
