SEOUL — Until recently, South Korea did not exist as far as the Communist world was concerned.
As the Communists saw it, there was only one Korea, and that was North Korea. They supported it militarily, economically and diplomatically.
But much has changed over the past six months. Three Communist countries--including the Soviet Union, which announced the action Saturday--have set up trade offices in Seoul and allowed South Korea to do the same in their capitals. As many as four others are expected to follow suit.
According to wire service reports, the Moscow-Seoul accord, in the form of a memorandum, was signed by Vladimir Golanov, vice president of the Soviet Union's Chamber of Economy and Industry, and Lee Sun Kee, president of the state-run Korea Trade Promotion Corp.
Korean officials said a formal agreement will be signed in December when Lee visits Moscow.
Handle Consular Affairs
One official, requesting anonymity, said the two sides came to an understanding that in the absence of diplomatic relations, the trade offices will be empowered to handle consular affairs.
Hungary's premier, Karoly Grosz, has said he wants to visit Seoul, and the foreign minister of South Korea hobnobs with his Hungarian and Yugoslav counterparts at the United Nations.
The opening to the Communist world is "moving very swiftly," a Western diplomat remarked the other day. It is "pretty heady stuff" and has created high expectations in South Korea, some of which he described as unrealistic.
Some Koreans agree, among them former Prime Minister Kim Jong Pil, and are urging caution.
"There are people in our country who want to move forward by leaps and bounds," Kim said recently. "We will have to restrain them."
According to the Western diplomat, who asked that he not be identified by name, South Koreans see the breakthrough as a way to influence North Korea and lessen its threat to their security, which is shored up by the presence here of 42,000 U.S. troops. In this, he said, they have succeeded.
South Korea's security has been enhanced, he said, adding that the chances of North Korea starting a war "have decreased as the Soviets and Chinese begin to shift to a more balanced position between the north and south."
Not Sure of Soviet Support
He said the North Koreans can no longer be sure that the Soviets will support them if they start another war. It was North Korea's advance into South Korea that started the Korean War of 1950-53.
Another analyst, a longtime resident here, said that North Korea "cannot succeed in an attack on (South Korea) without Soviet and Chinese help, given the guarantee of an American response." But the key to security here, he said, is the Chinese and Soviet fear of a confrontation with the United States "on a North Korean timetable."
South Korea's overture to the north, he said, "only improves the atmosphere."
He and the diplomat both criticized what they called naive thinking and immature emotional responses by some South Koreans. But even so, the diplomat said, many of the South Koreans' expectations in their dealings with the Communists are "very realistic."
Events that only a short time ago would have been inconceivable are taking place with astonishing regularity.
On Sept. 13, Hungary agreed to an exchange of permanent missions, headed by diplomats with the rank of ambassador. This was the first de facto recognition of South Korea by a Communist government since the Korean Peninsula was divided in 1948. North Korea called Hungary's decision a "betrayal" and a "sellout."
On Tuesday, under a compromise worked out with Communist countries, President Roh Tae Woo will become the first South Korean leader to address the U.N. General Assembly. A North Korean representative, not yet identified, also will address the world body.
Showering Attention on Seoul
China and the Soviet Union, which once competed for influence in North Korea, are now showering attention on Seoul. Neither has offered recognition, but according to Hong Song Young, an assistant minister of foreign affairs, South Korea looks forward to establishing some kind of ties, if not full diplomatic relations, with both "within three to five years."
On Sept. 16, Soviet leader Mikhail S. Gorbachev said in a speech that "possibilities can open up for forming economic relations with South Korea."
It was the first time that any Soviet leader had publicly referred to South Korea by name. Although Gorbachev referred specifically to economic relations, he proposed a multilateral conference that would include both Koreas in order to reduce the possibility of a military confrontation on the Korean Peninsula--and this is a very "diplomatic" subject.
Soviet officials who visited Seoul during the Olympics followed up by suggesting that South Korea take part in the development of Siberia. Roh immediately approved the idea.
