International Tournament

Mlily Cup（Mlily梦百合杯世界围棋公开赛）is a Chinese international tournament created in 2013. The sponsor is a Chinese manufacture of mattress and bedding products, with Mlily as its main brand name. As it currently stands, Mlily Cup is run every two years, alternating with the Bailing cup. Mlily also famously sponsored the jubango between Gu Li and Lee Sedol in 2014.

Bailing Cup (百灵杯世界围棋公开赛) is a Chinese international tournament created in 2012. It is sponsored by Guizhou Bailing Group, a big Chinese pharmaceutical company. As a major supporter of Go, the company also in the past sponsored the Chinese domestic Bailing Cup which is not to be confused with the international tournament. As it currently stands, Bailing Cup is run every two years, alternating with the Mlily cup.

The Ing Cup (应氏杯世界围棋锦标赛) is a major international tournament sponsor by Ing Chang-Ki family through their charitable vehicle the Ing Chang‐Ki Wei‐Chi Education Foundation. It is held every 4 years coinciding with the Olympics.

Samsung Cup is a major international tournament established in 1996. Its full name is Samsung Cup World Open Baduk Championship. It is organised by Hanguk Kiwon and sponsored by the insurance subsidiary of Samsung.

The Limin Cup World Top Star Tournament（利民杯）is an international tournament held annually at the Chinese southern city of Hangzhou. The organiser Hangzhou Qiyuan is an official branch of Zhongguo Qiyuan, the Chinese national Go organisation. Hangzhou Qiyuan not only hosts its local League teams, but also the 2nd Chinese national Go squad, consisting of many young Go prodigies. China's vast territory means that it is impractical for all Go players to live and train in the northern capital city of Beijing. So a second base in Hangzhou becomes a good solution.

This is a bilateral team competition between China and Korea, sponsored by China Merchants Property, a real estate enterprise based in Shenzhen. In its current form, the tournament is reminiscent of the Lotte Cup held in 1990's.

Chunlan Cup World Professional Weiqi Championship (春兰杯世界职业围棋锦标赛) is the first major international Go tournament organised by mainland China. It is named after the main sponsor Chunlan Corporation, one of the 50 large Chinese enterprises and best known for its air-conditioning products. Since term 3, the tournament has been held once every two years. Early rounds are often hosted at the city of Taizhou in Jiangsu province where Chunlan's headquarter is based.

Huang Longshi, a Chinese guoshou of the 17th century, is widely regarded as one of the most accomplished go players in history. This tournament is named after him because it is held at Jiangyan, a small town in Jiansu province of China, known as Huang's hometown. The tournament was first introduced in 2011 as an international women's team tournament. In 2012 it became a win-and-continue team tournament for the three major Go-playing countries - China, Japan and Korea - apparently to replace the defunct Jeongganjang Cup.

LG Cup is a major international Go tournament that has been held annually since 1997. It is the successor to Korea's domestic Kiwang tournament and it is often referred to as "LG Cup World Kiwang Tournament". The organiser is Chosun Ilbo (조선일보), one of Korea's largest media groups. The sponsor is LG Corporation. It is not to be confused with the domestic Korean LG Cup (also know as LG Refined Oil Cup, discontinued).
