Chinese leader Xi Jinping on Tuesday attacked calls from some in the U.S. and its allies to limit their dependency on Chinese suppliers and block the sharing of technologies.

In a speech to representatives of leftist political parties in more than 100 countries, Xi said China�s ruling Communist Party has succeeded in raising the country from poverty and created a new model of development.

Such experiences should be shared and no country should �obstruct the development of other countries and harm their people�s lives through political manipulation,� Xi said.

�We must jointly oppose anyone engaging in technological blockades, technological division and decoupling of development,� Xi said.

Decoupling has become a byword from some in the U.S. and elsewhere for ending dependency on Chinese supply lines, especially for high-tech products such as smart phones and computers.

Xi�s speech, carried live online, comes days after he delivered a defiant address marking the Communist Party�s centenary, saying China will not be bullied and will punish anyone who tries.

Xi tends to alter his tone depending on whether he�s speaking to a domestic or international audience, according to analysts.

�Xi is a risk taker but he is not reckless,� said Steve Tsang, director of the China Institute at the University of London�s School of Oriental and African Studies.
