"Our defence forces are alert on the border. There is no such thing that they will come to this side and occupy our lands. There is no need to worry," Singh told reporters while reacting to reports of incursion along Sino-Indian border in Ladakh.
"The border with China is a porous border. There is several kilometers of distance between two pickets. They sometimes inadvertently cross to this side and sometimes they do play mischief as well," he said.
The deputy chief minister said necessary steps would be taken to prevent incidents of incursion.
"Whatever is needed to be done, we will do that. These things do take place but this should not have happened," he added.
"Once reports come to us and we will take necessary measures. The situation has changed. China knows well that there is a change in the government in New Delhi. It is now Narendra Modi's government here. It will be taken up at appropriate level," he said.
