South Korea will soon no longer be one of the few countries where Google Maps doesn't work properly, after its security-conscious government reversed a two-decade stance to approve the export of high-precision map data to overseas servers.

The approval was made "on the condition that strict security requirements are met," the Ministry of Land, Infrastructure and Transport said in a statement.

Those conditions include blurring military and other sensitive security-related facilities, as well as restricting longitude and latitude coordinates for South Korean territory on products such as Google Maps and Google Earth, it said.

The decision is expected to hurt Naver and Kakao - local internet giants which currently dominate the country's market for digital map services. But it will appease Washington, which has urged Seoul to tackle what it says is discrimination against US tech companies.

"We welcome today's decision and look forward to our ongoing collaboration with local officials to bring a fully functioning Google Maps to Korea," Google Vice President Cris Turner said in a statement.

South Korea, still technically at war with North Korea, had shot down Google's previous bids in 2007 and 2016 to be allowed to export the data, citing the risks that information about sensitive military and security facilities could be exposed.

Concerns about market control

The data in question is 1:5000 scale data, where 1 centimetre on a map represents 50 metres in actual distance. Google has argued it needs to export the data to provide real-time navigation information worldwide. This includes people researching South Korean destinations from overseas.

The conditions stipulate that Google must process map data on locally based servers and is only allowed to export data related to navigation and direction services that have been pre-approved by the government.

The South Korean government also reserves the right to request revisions to maps, and Google must set up a security incident prevention framework to respond to emergency issues.

Choi Jin-mu, a geography professor at Kyung Hee University, said the decision raised serious questions about market control and national security.

"Google can now come in, slash usage fees, and take the market. If Naver and Kakao are weakened or pushed out and Google later raises prices, that becomes a monopoly. Then, even companies that rely on map services – logistics firms, for example – become dependent, and in the long run, even government GIS (geographic information) systems could end up dependent on Google or Apple. That's the biggest concern."

Naver's stock ended 2.3% down after the decision on Friday, though Kakao gained 1.5%.

AMCHAM Chairman James Kim welcomed the decision, saying it "sends a positive signal about Korea's commitment to innovation, open markets, and ensuring a level playing field for global companies operating in Korea."
