Why is the border line between some countries -LRB- e.g. Egypt-Libya , US-Canada , Niger-Algeria etc -RRB- a straight line , whereas several other countries -LRB- India-Pakistan , Russia-China etc -RRB- share zigzag border lines irrespective of their terrains ?
China warned India not to complicate the border situation with a new road along the Macmohon line . How important is this warning for India ? Should Modi continue the plan ?
