Google Placates India, China With Different Map Versions

Google has hit upon an interesting way of placating both China and India over the way its map application displays Arunachal Pradesh, a region whose ownership is disputed by the two countries.

The Chinese version of Google Maps shows parts of Arunachal Pradesh as inside China’s borders. In contrast, the Indian version of Google Maps depicts the state as part of India.

But both of those depictions differ from the global version of Google Maps, which shows Arunachal Pradesh as disputed territory within broken lines on the map.

some other websites also have given intresting titles for this subject such as ‘Two countries, Three Mpas’.
