How do you cash in a CD issued by Bank of Cambodia?

There seem to be two banks that fit that name:  the Foreign Trade Bank
of Cambodia and the National Bank of Cambodia.  The latter is the
central bank of the country:

Here is a site with the names of the Foreign Trade Bank's correspondent banks:

IF the CD was issued by this bank, one of the correspondents should be
able to help you.  If they offer to send the CD for collection, be
sure to ask about charges and how long receipt of funds may take.

Good luck!

It is the National Bank of Cambodia

Here is a site for the National Bank with address and email addresses.
I would try to contact the bank directly and ask about the best way to
cash the CD.  IF they suggest that you simply mail it to the bank and
that it can send you a check drawn on a bank in your country for the
equivalent amount in your currency, that would avoid collection
charges, but it is, of course, a risk.  Send by registered or insured
mail, and keep a photocopy and copy of your correspondence.  IF the
National Bank says that it can only send a check in Riel, you would
then have to take that to your bank and have it collected  - more
charges and exchange rate expense.
They may also suggest a bank in your country that will send the CD for
collection.  You can also ask your own bank or a major bank in your
area about its sending the CD for collection.
I don't know if you need to endorse the CD, but maybe.  Another reason
to talk to a major bank first.

Good luck!
