"I hope @PMOIndia is able to resolve the 'stapled visa' issue so that I can also visit the Terracotta Army and Great Wall of China," Omar wrote on micro-blogging site Twitter.
Omar was referring the stapled visa issued by China for residents of Jammu and Kashmir and Arunachal Pradesh.
His comment came soon after Modi visited the Terracota Army heritage site in China.
"Waving at the crowd would be a better caption because 'interaction' actually requires people to interact," Omar wrote.
