Following the Vietnam War, Vietnam's T-54/55s and Type 59s continued to see much combat activity against neighbouring Cambodia and China to their north between 1978 and 1979. Just like many developing countries around the world which continue to operate the T-54/55, at least 900 T-54s, along with a similar number of T-55s and Type 59s, are still in active military service with the Socialist Republic of Vietnam until the present day. Some of them are slated to be replaced by the more modern &lt;a href="T-90"&gt;T-90S/SK&lt;/a&gt;.
