South Korea announces symbolic, new sanctions on N Korea

South Korea has announced a set of largely symbolic, additional sanctions on North Korea for the nuclear and missile tests it conducted this year.
Today's announcement came two days after the UN Security Council voted to tighten sanctions on North Korea. Pyongyang has warned of unspecified retaliation.
Seoul says it blacklisted dozens of new North Korean officials and entities by banning South Koreans from engaging in financial dealing with them.
A Seoul statement says it'll sanction a China-based company for allegedly assisting financial activities by a North Korean bank sanctioned by the UN.
It's unclear if the South Korean measures will sting North Korea. Inter-Korean trade and exchanges largely remain suspended and Pyongyang is already under multiple rounds of UN sanctions. The Chinese company has no assets in South Korea.
