Former sprinter Sumariwala, IOA vice-president Tarlochan Singh and more than 50 competititors, including the women's hockey squad, was present when the Indian flag was hoisted along with those of five other countries/region - Myanmar, Uzbekistan, Tajikstan, Chinese Taipei and Palestine.
Sumariwala, while speaking to reporters ahead of the ceremony, said that the Indian contingent members were quite satisfied with the accommodation though it was a bit cramped.
The athletes, who reached in first batch were initially having problems with food but Sumariwalla said that it has been sorted out to some extent.
"They complained that they were not getting Indian food and it has been rectified to some extent, for example dal is being served," said Sumariwala.
Sumariwalla also exuded confidence that the Indian contingent would better its show in Guangzhou but did not want to predict the medal count.
