The firing incident also dealt a blow to South Korea's tourism, as many people in Taiwan have either cancelled or delayed their planned trips to the country over the past two days due to safety concerns, though the government has not raised its travel alert for this destination so far.

The peak season for travel to South Korea is autumn and winter, with the biggest attractions being appreciating maple leaves or skiing.

But after the unexpected flare-up in the Korean Peninsula that happened at around 2 PM on Tuesday afternoon Taipei Time,

local travel agencies specializing in travel tours to South Korea have been receiving tons of phone calls, asking for cancellation or change in plans.

Travel agents estimate that the impact on these two days would be minimum as most consumers would wait and see before making their decisions.

And the next week is the critical period.

Local tour guides in South Korea said the atmosphere is as normal as usual while other travel groups from around the world currently in the country continue their plan.

So far the Ministry of Foreign Affairs hasn't issued a travel warning for South Korea.

Therefore, those who wish to cancel the plan would have to pay a penalty, which varies according to the length of time before departure, based on a standardized travel contract.

Association of Travel Agencies estimates that there are around 3,000 Taiwanese travelling in South Korea now.

As reported, they are all safe.
