China filed an appeal with ISO over wireless technology developed by Intel, trying to end Intel's dominance in WLAN encryption standards.
A Chinese industry group, WAPI, has accused the US Institute of Electrical and Electronics Engineers Inc (IEEE) - which created the standard championed by Intel - of violating ISO rules.
WAPI and the IEEE applied to the ISO for a new international standard last October, but WAPI's application was rejected in fast track ballot in March.
China claims that IEEE broke ISO regulations when national bodies voted on new technology to fix security loopholes in the WLAN standard.
