In 1992 Angkor as a whole was inscribed as a World Heritage Site; the following year an international coordinating body gathered the restoration teams of various countries. French, Japanese, Indian, German, American, Chinese and other teams each took a section; in 2002 the upper west facade was propped with scaffolding, and in 2005 the Japanese team finished the library on the outer north side.
Sandstone's enemy is water and microbes. Surveys found a biofilm on the surface slowly eating the stone, which is why the reliefs are now the most carefully watched part. Walking the galleries, where the newly added stone is paler than its neighbour, is mostly the patching of these last decades.
