"Chinese delegation was invited for the show but so far they have not come and not given any intimation," he said at a press conference at the military show.
Defence Ministry officials said though the delegation from that country was invited, Chinese military hardware firms were not allowed to take part in the show as exhibitors.
The development comes at a time when India and China have signed a Border Defence Cooperation Agreement and are in the process of developing mechanisms for having a better understanding between the two Armies at the borders.
"After the talks, there has been a dive in the number of such incidents but the real test will be in the summer months," he said.
Commenting on the situation in Afghanistan, the Defence Minister said India has "no military role" in that country but it was concerned at the fallout of the withdrawal of the US forces from there by the end of this year.
