What are the top 3 exports of Korea?

Could you please elaborate on the following question: "What are the three most significant exports of Korea?" I'm particularly interested in understanding which goods or services hold the greatest economic importance in terms of export revenue for the country. Additionally, I'm also curious about any trends or patterns in these exports, such as whether they are primarily industrial goods, agricultural products, or technology-related items. Could you provide some insights into these exports' contribution to Korea's overall trade balance and economic growth? Thank you for your assistance.
