"My US trip has been criticised by some people but they should understand that such visits are not pleasure trips. Until and unless we visit other countries and learn about the latest advancements, how can we introduce such things in our own country?" he told reporters here.
"We send officials also on study tours. Even journalists should also accompany us," he said.
Gogoi, who returned from the official tour on Sunday, said during his US visit he had seen and discussed latest technology and know-how related to various fields, including flood-control, education and health.
"Our aim is to mitigate hardships with the use of latest technology. We want to channelise and reclaim land lost in the Brahmaputra. Such things take time - even 50 years, but we want to make a start to the process.
"I have even visited children's parks and museums but not for fun. I went to see how in other countries kids are given lessons in culture, history and manners," he said.
