A Foreign Relations Department official says Mexico will send a plane to China to bring back citizens after the Asian country quarantined more than 70 Mexican travelers in its fight against swine flu.

The official says the government will charter an Aeromexico airliner in the coming hours to take home any Mexicans who want to leave China. The official spoke on condition of anonymity Sunday because of department policy barring her from being named.

The official could not say if priority would be given to Mexicans who have been quarantined.

Earlier Sunday, Mexican President Felipe Calderon expressed dismay that "some countries or places are taking discriminatory measures because of ignorance and misinformation."
