The IPO market has been hot this year, with more than 200 offerings 
raising over $70 billion. Of these IPOs, 30 were Chines companies, 
making 248 U.S. exchange listed China-based companies totaling $2.1 
trillion in market value. Now, new rules
 by the Chinese government may slow Chinese domiciled companies listing 
on U.S. exchanges. The Chinese State Council stated that it would update
 the rules for "the overseas listing system for domestic enterprises"and
 tighten restrictions on cross-border data flows and security. China has
 already launched an investigation into ride-hailing app Didi. And 
Nasdaq-listed Weibo has announced plans to go private.
