The Opening of the South-North route (打通南北航线) was symbolized by the passage of the ship Liming (黎明轮) from Zhanjiang, GuangdongtoQingdao, Shandong on 5 April 1968. Mainland China resumed using its own ships to carry out sea transportation and shipping between its north and south ports.
In 1949, after the cross-strait split and the PRC participating in the Korean war, the ROC with support of the US government began military blockades of the Taiwan strait. This was part of the Guanbi policy. The PRC, unable to launch a military counterattack, could only hire foreign ships to carry out shipping, thus disrupting the shipping of its own ships between the northern and southern ports on the Chinese mainland.
In May 1966, premierZhou Enlai of the State council approved the report of the Ministry of Communications on opening the north–south route. On 25 April 1968, the Liming (黎明轮, The Dawn) made the following voyage: [add image / map]
Between June 2–14, it made its return to Zhanjiang via the reverse route.
From September 22 to October 4, the Jiujiang (九江, Ninth river), belonging to the Guangdong Ocean shipping company took the same route. On October 22, Zhou Enlai officially approved the opening of the north–south route.[1]
In February 1972 Nixon visited China, signaling a détente in US-China relations. In October, the Wuzhishan (五指山轮) sailed from Hainan Basuo port (八所港) to the Dalian port, greatly shortening the north–south route. In July 1974, the Yangmingshan (阳明山轮) sailed from Zhanjiang port to Qingdao, shortening the route even further.[2]
However, because mainland ships cannot typically pass through the Taiwan strait, the South-North route for a long time had to detour around the Pacific. Only in 1979 did shipping resume across the Taiwan strait.
