If "nothing" can FTP to china... maybe.  Are you getting the error on
the initial connection, or once you attempt a transfer?

If on initial connection, insure "the firewalls" permit port tcp/21
inbound to China.

If on initial transfer, insure "the firewalls" permit port tcp/20
*outbound* from China.

If you can get an initial connection, you might try "PASV" mode in FTP
once you connect (can cause other errors on it's own, but will deal with
that when they come up :) ).

Did this "just come up" out of the blue after working before, or is this
the first attempt?  You might check INETDSEC.NET to see if ftp is
allowed in, or if there is any interference.  If there are IP
restrictions, insure your source networks are defined in the China-side
INETDSEC.NET.
