Heads of 20 parties, including the Congress, participated in the virtual meeting, called in the wake of the India- China border clash in Ladakh's Galwan valley which martyred 20 Indian Army personnel late on Monday night.
Presidents of various parties, including the BJP, Congress, TMC, AIADMK, DMK, TRS, JD(U), BJD, LJP, BSP, SP, Shiv Sena and NCP among others, are taking part in this virtual meeting.
Opposition parties, including the Congress, have asked the government to be transparent on the border situation.
The Congress has been attacking the NDA government over the last few days over its handling of the issue.
In his first comments on the issue on Wednesday, Prime Minister Narendra Modi asserted that the sacrifice of Indian soldiers will not go in vain.
