"The present wave of anti-China sentiment has now evolved into an unpleasant, even racist, sinophobia, which threatens international peace and security," Horton said in an opinion article recently published by The Guardian.
"At moments of geopolitical stress, it is surely better to intensify, not weaken, personal and institutional relationships. It is surely better to build better understanding between peoples," Horton added.
"China's 1.4 billion people are not immune from the economic shocks that are currently enveloping the world. A pandemic is a moment for solidarity between peoples, not conflict between governments," he continued.
A pandemic is a moment for "conciliation, respect, and honesty between friends", Horton noted.
Instead of accelerating a new cold war between the West and China, Horton called on medicine and medical science to help establish a new compact between nations.
He also praised China's scientists who acted "decisively and responsibly" to protect the health of the Chinese people in the case of COVID-19.
"They advised early lockdown to cut the lines of viral transmission. They implemented strict physical distancing policies to reduce social mixing. And they built temporary hospitals to expand bed capacity and to enable triage of the sickest patients to intensive care," he stressed.
Global COVID-19 deaths surpassed 707,000 on Thursday, according to the Center for Systems Science and Engineering at Johns Hopkins University, while virus cases has topped 18.8 million.
