Dear Representative Chen:

I have the honor to refer to the recent agreement reached betwe-
en the representatives of the American Institute in Taiwan (AIT)
and the Taipei Economic and Cultural Representative Office in
the United States (TECRO) concerning the Asia Pacific Economic
Cooperation Mutual Recognition Arrangement for Conformity Asses-
sment of Telecommunications Equipment (APEC Telecom MRA). The
agreement, as embodied in this letter and in your return letter,
shall become effective upon AIT's receipt of your return letter.

AIT confirms that the United States will apply the general prov-
isions, Appendix A, and Phase I Procedures in Appendix B of the
APEC Telecom MRA to telecommunications equipment from Chinese
Taipei. The APEC Telecom MRA is attached to and an integral pa-
rt of this letter.

In particular, the United States will apply the Phase I Procedu-
res in Appendix B for the recognition of testing laboratories
designated by Chinese Taipei as Conformity Assessment Bodies (
CABs) and the acceptance of test reports from recognized Chinese
Taipei CABs for conformity assessment of telecommunications equ-
ipment with the Technical Regulations of the United States. Att-
ached is the list of Technical Regulations for which the United
States will accept test reports from recognized CABs. Any modi-
fications to this list shall be notified in accordance with the
general provisions of APEC Telecom MRA.

I also am pleased to inform you that the National Institute of
Standards and Technology (NIST) is the Designating Authority for
the United States. NIST may designate testing laboratories in
accordance with the general provisions and Appendix A of the AP-
EC Telecom MRA for recognition as CABs by Chinese Taipei. The
United States understands that it will be necessary to exchange
information on the technical criteria for accrediting CABs. The
FCC is the point of contact for the United States for activities
under this mutual recognition arrangement.

Except, however, the Occupational Safety and Health Administrat-
ion (OSHA) is the point of contact for the United States for el-
ectrical safety.

AIT further confirms that the United States will undertake steps
with Chinese Taipei for mutually satisfactory implementation of
the Phase II Procedures in Appendix C of the APEC Telecom MRA
with the goal of beginning such implementation as early as poss-
ible after completion of necessary domestic procedures.

Sincerely,
