What will you do if your neighbour says you cannot sip tea sitting in your lawn? Won't you want to give him a tight slap that keeps ringing in his ears forever?

Wish it was possible in this case as well. China on Tuesday raised objections to Indian Prime Minister Manmohan Singh's recent visit to Arunachal Pradesh. The prime minister had been to this part of India on campaign trail for the state assembly elections. This is what a statement said on the website of China's foreign ministry.

China expresses its strong dissatisfaction on the visit by the Indian leader to the disputed area in disregard of China's grave concerns. We urge the Indian side to take China's solemn concerns seriously and do not stir up trouble at the disputed area with a view to ensuring the sound development of China-India relations.

The Indian government, as usual, was "disappointed and concerned".
