Snow height or rock height?   Chinese and Indians disagree on even how to measure the height of the world's highest mountain, since if you have ever had one of those 'why can't they just talk to each other?' moments about actual serious geopolitical issues, you know it is never that simple.

Mount Everest is in both countries and its official height 29,029 feet and both sides agree that is the official height, but the pesky Chinese still use their rock height number instead of the snow height number, which is 12 feet higher.  So Nepal says it will take an accurate measurement.

Both countries could be wrong.   The US Geological Survey used GPS in 1999 and say it is approximately two feet higher than the official number.
