China has reportedly depicted Arunachal Pradesh and Aksai Chin as part of its territory in its new passports.
China irked Vietnam and the Philippines as it also included disputed South China Sea Islands on maps printed inside new passports.
According to media reports, the Philippines 'strongly protests' against China's move, its foreign affairs ministry spokesman, Raul Hernandez, said.
"The action of China is contrary to the spirit of the declaration of conduct of parties in the South China Sea," Hernandez said.
Vietnam's government lodged a formal complaint with the Chinese embassy in Hanoi. (ANI)
