China's military on Thursday expressed concern over India's plan to construct 54 new border posts in Arunachal Pradesh, saying India should not complicate the situation and do more to maintain peace as it is a "disputed area'.

"We have noticed relevant report. Dispute still exists in the eastern part of China-India border,' Defence Ministry spokesman Yang Yujin told a media briefing in Beijing when asked about the plans announced by the Union Home Ministry to build 54 new border posts along the border in Arunachal Pradesh.

"We urge the Indian side to do more to maintain peace and stability in the area and not do things that may complicate the situation,' he said.
