Ahead of Prime Minister Narendra Modi's visit to China in June, Defence Minister Nirmala Sitharaman has said that India is "alert and ready for any unforeseen situation" in Doklam, where the two countries were locked in a face-off situation for 73 days last year.

Speaking to reporters in Dehradun on Sunday, Ms Sitharaman said, "We are alert and ready for any unforeseen situation in Doklam... we are constantly working on the modernisation of our forces and will maintain our territorial integrity."

On whether India has taken it up the matter with China, Ms Sitharaman had said issues relating to the border are regularly taken up with the Chinese side through diplomatic channels and at Border Personnel Meetings, flag meetings and meetings of Working Mechanism for Consultation and Coordination on India-China Border Affairs.

PM Modi is expected to take part in the Shanghai Cooperation Organisation (SCO) summit, to be held in Qingdao, on June 9 and 10. Sources say a bilateral meeting with President Xi Jinping is also on the cards.
