IV. Passage Completion (10%)
      Yanji, a border town in China’s cold and poor northeast abuts North Korea along Tumen River, where a bridge serves as the gateway for a lively commerce in shellfish plumbed from the Sea of Japan off North Korea.   31   The trade between these two countries is dominated by China’s purchases of cheap North Korean iron ore and coal.
      By encouraging trade with North Korea, China aims to prevent North Korea’s government from collapsing, an outcome that could result in a Korean Peninsula allied to the United States.   32   It is estimated that two million ethnic Koreans live there.
      That is where the crabs come in. Scooped from 915-meter-deep waters by trawlers crewed by North Korea workers, the crabs are first brought to the North Korean port of Rason, a special enterprise zone serving foreign investors and largely financed by China. The crabs are trucked in ice to the Chinese border town of Quanhe, and then brought to the market in Yanji,or flown to cities across China as a delicacy for the affluent.
      Yanji offers a peep into forbidden territory. People here, especially the ethnic Koreans, talk of a love-hate relationship with their neighbor, run by one of the most isolated and brutal governments in the world.   33   The shadow of North Korea can be felt in many ways here. Refuges protect defectors from North Korea who are brave enough to risk escaping across the Tumen River. Shops sell North Korean food like ginseng root, and powder ground from the gall bladder of bears.
        34   They sell not only to upscale restaurants around China, but also to banquet organizers. The sales pitch stresses what is called the purity of the waters around impoverished North Korea compared with the more polluted seas around industrialized Japan and South Korea.   35   China will continue to invest in Rason, where business conditions had steadily improved.
(AB) Business with North Korea also serves a domestic goal: It helps employment and incomes in needy Jilin Province.
(AC) For Chinese traders, importing crab is a lucrative business.
(AD) Though China is North Korea’s biggest investor, the North Korean government distrusts the traders, keeping them apart
from North Korean workers.
(AE) It is believed that North Korea’s recent nuclear tests would have few consequences for this business.
(BC) It is an exotic niche business in the more than $11 billion annual trade between North Korea and China.
(BD) For the repressed people of North Korea, there appears to be sympathy among residents on the Chinese side of the border.
