Peter Hillary will always call the world's tallest peak Mt Everest even though China wants Westerners to call it Mt Qomolangma.
China has launched a campaign accusing British "colonialists" of "ignorance and arrogance" by continuing to refer to Everest.
"British colonialists raped the sacred mountain of the Tibetans by giving it a false name," one report said.
"Until today the world is still persistently humiliating Mt Qomolangma with English-language hegemonism."
China wants the name changed before next year, the 50th anniversary of the first ascent by Sir Edmund Hillary and Sherpa Tenzing Norgay on May 29, 1953.
The mountain became known as Mt Everest in 1865 in honour of Sir George Everest, the Surveyor-General of India who mapped the 29,028ft peak in 1852.
Mt Qomolangma is the Chinese equivalent of the Tibetan name for the mountain, Chomolungma, meaning Mother of the World.
The Nepalese call it Sagarmatha or the Goddess of the Sky.
