China's construction on its own islands and reefs in the South China Sea is lawful and justified, as China is merely building facilities in its own yard, Foreign Minister Wang Yi said Sunday.

Wang made the remarks at a press conference on the sidelines of the annual session of the National People's Congress, China's top legislature.

"China is carrying out necessary construction on its own islands and reefs. The construction does not target or affect anyone," Wang said.

Wang said China was not like some who engaged in illegal construction in another person's house, and the country does not accept criticism of others when it is merely building facilities in its own yard.

"We have every right to do things that are lawful and justified," Wang said.

He added that China will continue to uphold freedom of navigation in the South China Sea, continue to peacefully resolve disputes through direct dialog and consultation, and continue to play a constructive role in maintaining regional peace and stability.

China's policy toward its neighbors is guided by the principles of amity, sincerity, mutual benefit and inclusiveness. It aims to bring harmony, stability and prosperity to the neighborhood.

"This policy has not changed, and will not change," according to Wang.
