China considers Taiwan its 23rd province; and Hong Kong a special administrative region. Forces include People's Liberation Army (PLA), which includes the Ground Forces, Navy (includes Marines and Naval Aviation), Air Force, Second Artillery Corps (the strategic missile force), People's Armed Police (internal security troops, nominally subordinate to Ministry of Public Security, but included by the Chinese as part of the "armed forces" and considered to be an adjunct to the PLA in wartime). Web Address: http://www.fmprc.gov.cn/ Notes on Operation: Distinctive 4+4 VFT system still in use, but appears to be under replacement by MIL-188-110A PSK HF modem and MIL-188-141A ALE combination during early 1998. 4+4 still appears to be the modem-of-choice for difficult, long-haul circuits. MFA and embassies are migrating (late 1999) to standard Microsoft Office (with Outlook email) software allowing message transfer across IP-over-radio circuits using the MIL-188-110A modems. ALE identifiers appear to use two different schemes, with three digit trigraphs or letter-letter-3 digits-letter formats. Voice coordination is common before and after message transfers and during link set-up.
