Police spokesman Ganesh K.C. said the security was stepped up Monday to stop any possible protests in Katmandu.
Police officers in riot gear guarded all the roads leading to the Chinese embassy and its visa office.
Police are also keeping a close watch at the Boudhanath area in Katmandu where most of Tibetan refugees live. Two people self-immolated in the area last year to protest against China.
Nepal does not allow such protests, saying it cannot allow activities against friendly nations.
