India on Thursday said Chinese patrols do "stray" across to the Indian side but downplayed such incidents holding that its boundary with China is one of the "most peaceful and tranquil."

"We have a very long boundary with China. The Line of Actual Control (LAC) with China has not yet been delineated and, therefore, since the Line has not been delineated, there are differences in perception which is very natural and I said it is a long border.

"So from time to time, the patrols do stray across. This is not new. This does happen. But when it happens, they revert to their areas," official spokesperson in external affairs ministry Vishnu Prakash said.

He was responding to questions on reports of recent incursions by Chinese patrols along the LAC.

"I would like to highlight that India-China boundary is one of the most peaceful, one of the most tranquil boundaries that we have," he said.

Prakash said India and China have a "very good mechanism" and if there is any issue pertaining to such incursions, they are "immediately taken up and amicably resolved".

To another question about the recent reports that one of India's most wanted and global terrorists Dawaood Ibrahim's son's marriage reception was being held in Pakistan, he said the 'most wanted' list has been shared with Pakistan.

"We have taken up this issue of most wanted people who we believe are in Pakistan or territories controlled by Pakistan.

They have told us that these people are not there, specifically about Dawood Ibrahim that he is not there".

Asked whether it was not obvious that Ibrahim was there because of the reception, he said, "That is precisely my point", implying that there was contradiction in what Pakistan was saying and the actual situation.
