Here are the changes in the Mount Everest permit process:
Climbers must submit proof of having scaled at least one 6,500-metre peak in Nepal. Critics argue limiting the provision to Nepal makes no sense.
Climbers must produce a certificate of good health. Critics say it is easy to forge such certificates or find a compliant doctor.
Guides must have three years of experience organising high-altitude climbs. Critics say so many Sherpas can claim such experience that virtually all outfitters will qualify.
