"In this context, it is important that the presidential elections take place as scheduled," Kumar said.
"We will participate in all formats of talks which could bring peace and security in the region," he added.
Kumar's comments seemed to back Afghan President Ashraf Ghani's call on the Taliban to engage in "serious talks" with the government in Kabul after the Taliban rebels and the US reported progress during unprecedented negotiations in Qatar last week.
"I call on the Taliban to... show their Afghan will, and accept Afghans' demand for peace, and enter serious talks with the Afghan government," Ghani said in a nationally televised address from the presidential palace in Kabul on Monday.
Though both the Taliban and the US have cited "progress" in their peace talks, sticking points still remain.
These include a ceasefire and a timetable for the withdrawal of foreign troops, as well as a prisoner exchange and a guarantee not to allow militant safe havens in Afghanistan believed to have been on the agenda.
