The torch route has faced several protests during its journey so far, mostly over an alleged Chinese crackdown in Tibet.
But the Dalai Lama, the Tibetan exiled spiritual leader, said on Thursday that China has the right to host the Olympics, which are due to go ahead in August.
"I support the Chinese host for the world game because China is the most populous nation, ancient nation," he said.
Also on Thursday, Chinese police said that it had uncovered a plot to kidnap foreign journalists, tourists and athletes during the Olympic Games.
"The violent terrorist group plotted to kidnap foreign journalists, tourists, and athletes during the Beijing Olympics and, by creating an international impact, achieve the goal of wrecking the Beijing Olympics," Wu Heping, a spokesman for China’s ministry of public security, said.
The kidnap plan was devised in the remote Xinjiang region, which has a strong Muslim population of Turkic-speaking Uighurs.
In the other case, police in January broke up a group "sent from abroad" by the East Turkestan Islamic Movement to stage attacks with explosives and toxic materials during the Olympics, the Chinese government's website said.
