India today said there is nothing unusual about US Ambassador Richard Verma's recent visit to Tawang in Arunachal Pradesh. <br/><br/>Reacting to China's objection to the visit, External Affairs Ministry spokesperson Vikas Swarup said, Mr Verma visited Arunachal Pradesh at the invitation of India which is its integral part. <br/><br/>Mr Swarup said, Mr Verma is accredited to India and therefore there is nothing objectionable in his visit. <br/><br/>Taking exception to the visit by Mr Verma, China had said it was firmly opposed to it and that any interference by Washington in the Sino-India boundary dispute will make it more complicated.<br/>
