"We will not take anything that is not ours, but we will defend every inch of territory that belongs to us," Chinese Foreign Minister Wang Yi told mediapersons here in his annual press conference on the sidelines of the ongoing National People's Congress (NPC) session.
There was no direct reference to India in his press conference, while he launched a frontal attack on Japan and made strong comments about smaller maritime neighbours who contest China's claims over the South China Sea.
"We will never bully smaller countries, yet we will not accept unreasonable denunciation from smaller countries," he said regarding China's neighbourhood diplomacy, especially in the South China Sea.

"There will not be any change to this position," he said.
"We will more actively practise our neighbourhood diplomacy guideline of amity, sincerity, mutual benefit and inclusiveness."
