Besides the missionaries some other foreigners that would end up being buried in Yanghwajin were ex-servicemembers that married local Korean women and made Korea their permanent home.

Many of those who died in the late-60s / early-70s (those whose grave markers are shown above) weren’t ex-service members – they were active duty combat casualties in Vietnam.

I assume they had Korean wives who stayed in Korea while they were deployed to Vietnam – they got killed in Vietnam – and the decision regarding the disposition of their remains was left to their spouses – who opted to have them brought to Korea for internment.

There is a fairly large section of US military graves there with dates of death during the Vietnam era.

I work with someone whose father was killed in Vietnam while he and his Korean mother were living in Seoul. Even after his father was killed, he was allowed to continue attending school on base for several years until he graduated from SAHS.
