Which countries recognize the McMahon Line?

The maps published by major countries in the world all draw McMahon line, following the drawing principle based on the actual control line. It's not recognized ... I've never seen it ...

Indeed, Aksai Chin is marked as a disputed area on most maps, and the disputed national boundaries are used to draw China's claim line, that is, the actual control line and the Indian claim line. But in Abang, the actual control line, that is, McMahon line, is often drawn as a disputed boundary, while China's claim line is rarely drawn. On this issue, I have to say that it is biased towards India.

At the same time, it should be noted that on the maps of large mainstream websites, such as google and bing, both parties draw claim lines at the same time.

Different countries have different national identification standards. According to China's standards, the main ethnic groups living in Abang should be Barrow and Menba, who are members of 56 ethnic groups. Among them, the concept of Barrow nationality has not been widely recognized by academic circles, and many people think that "Barrow nationality" is actually many different nationalities.

Indian immigrants are not sure whether they are Luoba or Menba. These immigrants come from the northeastern states of India, but also from the interior of India and Bangladesh.
