Four technology students from Wuxi Children's Palace took part in an international youth conference on the development of the world over the next century in Sagamihara, Japan recently.

A total of 55 children from countries including Ukraine, Canada, China and Japan took part in the six-day event.

The event was supported by the governments of Wuxi and Sagamihara as part of their celebrations to mark the 30th anniversary of the establishment of friendly relations between the two cities. The children from Wuxi took part in a number of discussions during the conference, with the group's leader Xin Wen, a student from Wuxi Foreign Language School, addressing the event on the topic "if there were 10 billion people on the earth after hundred years, what would happen?"

"The students from Japan are younger, so they just consider the topic from the perspective of making more friends, while I express my ideas in terms of resource and environment," said Xin.
