Korean Wave or in Korea called hallyu wave a term used to describe the results of South Korean pop culture that was successfully exported to other countries such as in Asia, Europe and America. And in recent year, Korean waves culture has become popular which is represented by Korean music, Korean dramas, and Korean culture and don't forget that Korean idols are also be a main actor in the heart every fan k-wave in the world.
In my country,Indonesia,the Korean wave has been known since the beginning of 2000, The presence of the Korean Wave was first marked by the presence of Korean dramas that managed to captivate Indonesian audiences, the rise of Korean dramas that entered Indonesia seemed to open up new avenues for other Korean cultures to enter Indonesia.
According to data from the Korea Tourism Organization in 2008, there were 80,000 visitors from Indonesia visiting South Korea and increasing every year. In fact, in 2017 the data has reached 230,000 visitors.
This shows how much enthusiasm the Indonesian people have for South Korea, especially after the entry of the Korean Wave to Indonesia. For me it's normal, especially in the era of globalization when the development of technological sophistication and internet access is very easy and for the spread of the Korean wave virus is no longer impossible because it is supported by platforms such as Youtube, Facebook, Twitter, and more.
And what cannot be forgotten is that in 2017-2018 the world seems to be attacked by viruses from the Korean wave, not only in Indonesia but other countries in the world such as participating and supporting Korean wave viruses, for example, at the closing ceremony of the Asian Games 2018 super junior boyband from SM entertainment and  ikon boyband from YG entertainment became the main actor to increase excitement after the closing ceremony of the Asian Games in Indonesia.
Aand when the led show was opened, the exo boyband with power song titles was played in the world's tallest building, burj khalifa and did not miss the closing ceremony held at the Russian dj stadium, fake love songs from BTS and power songs from EXO also celebrated at the closing ceremony and many more.
In the development of the very fast Korean wave in my country and other countries in recent years, makes me want to learn deeply and look for facts about cultural developments in Korea. I was very impressed when discussing the culture and development of the Korean wave in South Korea, for me South Korea has a unique culture because as a developed and modern country.
South Korea is still able to maintain the traditional side of the country itself.And here I also think that South Korea has a very large Korean wave of interest all over the world and this Korean wave can also be used by the South Korean government in cooperating and building unity among countries around the world.
The advantage of using Korean waves for diplomacy is very effective and efficient because the South Korean government only uses the touch of art and works of South Korean artists to introduce South Korean identity to international countries so that other countries want to try to establish good cooperation with South Korea.
And these steps can be used by the South Korean government in building diplomacy with other countries using the influence of the Korean wave.
 1.Exporting good quality Korean dramas in other countries.
Korean drama is the beginning of the spread of hallyu waves to other countries, good acting from Korean artists is one of the attractions for fans of Korean dramas, short episodes make the audience not feel bored quickly and can easily follow the storyline and most of all is the audience can be carried away.
2. Hold more concerts for Korean boyband and girlband groups in other countries.
South Korea's Boyband and Girlband groups are very beneficial for Korea, because they can improve the country's economy and introduce South Korean culture, more concert tours will slowly add to the country's deficit, in Asia around 70% of the human population lives in the asia continent and this is a good opportunity for the Korean government to build cooperation and improve state finances by touring in other countries. accidentally kpop fans will think well of the country of South Korea and accidentally also the South Korean government has cooperated with other countries subtly.
 3. Held Korean Idol Fansign and Fanmeeting.
here are so many kpop fans who want to dream of meeting and interacting directly with their idols. This is a strategy that can be taken by the Korean government in building cooperation and gaining trust from other countries.
4. Make promotions about tourism in South Korea through idol k-pop.
South Korean tourism is indeed a paradise for lovers of Korean waves, ranging from South Korea's natural beauty, clean environment, unique culture and celebrations, fine cuisine, to global fashion in South Korea. The introduction of South Korean tourism is one of the events to be closer to other countries so that other countries know about South Korea, tourism promotion supported by Korean idols is one of the attractions for Korean wave fans.
5. Promote k-beauty in other countries.
South Korea is a haven for the world of fashion ranging from cosmetics to global labeled clothes all in South Korea, the South Korean government can take advantage of this situation to promote beauty to women in other countries who want to understand South Korea's beauty standards. and this will attract women to visit and give a good impression of South Korea.
6. Open branches and entertainment agency offices in other countries.
large entertainment agencies are very influential in South Korea because this entertainment agency is one of the economic supporters in South Korea, the best idols are supporting an entertainment agency to continue to bring interesting entertainment, opening branches and entertainment agency offices in other countries intended to establish cooperation and gain trust from the other countries and facilitate access for k-wave fans to get detailed information from the central entertainment agency office, and the opening of an agency's office can also be used to recruit new idols from that country.
 7. Introduced the application made in South Korea.
The South Korean application is special for connoisseurs of the Hallyu wave world because this application makes it easy for users to better understand South Korea, and also through this application Hallyu Wave lovers have their own world. This can be used by the South Korean government to introduce Korean culture through applications, chat applications like Linee and Kakaotk have increased in use, and this free comic webtoon application platform can be used by artists to show their creativity.
That is some effort that can be made by the South Korean government to build cooperation and diplomacy and attract the sympathy of the government and citizens of other countries, especially for fans of the hallyu wave through the Korean wave.
For me diplomacy does not always have to use sentences and words, because there are many ways for diplomacy in terms of reaching a diplomatic agreement can use a variety of unique and interesting ways and if South Korea diplomatically uses Korean waves this method can greatly benefit both countries in terms of this Korean government must pay attention to the industry in the world of entertainment and the world of fashion because the world of entertainment and the world of fashion is one of the pillars of the existence of the Korean wave and a very easy way for South Korea to establish cooperation and friendship with other countries in the world so that South Korea gets good image in the eyes of the world.
