Since the age of 13, Clinton Yong-Jin Lee has participated in numerous commemorative events, including 6,000 Red Poppies for Peace and Remembrance and the 70th anniversary of the Battle of Kapyong Memorial Walk.
In 2018, Clinton was a leading participant in the “6,000 Red Poppies for Peace and Remembrance” event and assisted with placing 4,000 poppies on the headstones of Veterans to commemorate the 100th anniversary of the First World War. Since then, he has participated in the 70th anniversary of the Battle of Kapyong Memorial Walk, a 300 km memorial walk from the Kapyong Battle Memorial on Radar Hill near Tofino, British Columbia, and ended at the Kapyong Stone Korean Memorial in Langley, British Columbia. Although Clinton did not walk the entire way, he did walk along with Guy Black during the last two days, from Ladner to Langley, walking 65 km in less than 24 hours and participating in the wreath-laying ceremony at the end of the walk.
In 2023, at the age of 18, Clinton participated again in the South Korean portion of the Korean War 70th anniversary Memorial Walk for Peace and Veterans, a 300 km 10-day international memorial walk in Canada and South Korea. The walk began in Langley, British Columbia, at the Kapyong Stone Korean War Memorial, and went to Vancouver International Airport, and continued from Incheon International Airport in South Korea to Kapyong County and Pocheon-si. Clinton walked with Guy Black and quickly became the most significant supporter of the memorial walk in Korea, walking with Guy Black every day and acting as his translator and navigator which was extremely difficult to follow due to the Korean – English language barrier and the long complex route. Once they reached the peak of Kakhul-Bong Hill 467, Clinton participated in a tribute to Private William Leslie Strachan, a wreath-laying ceremony at the Veteran’s monument in Pocheon-si, with Korean War Veterans, the Korean Army and county officials, and even appeared as a member of an approved delegation at the Canadian monument for the Battle of Kapyong. The memorial walk attracted media attention from newspapers, radio and television news in Canada and South Korea. Clinton appeared in newspaper articles such as the Stars and Stripes and the Korea Broadcasting System where he was able to bring positive attention to Canadian Korean War Veterans.
