Jilin province and Sakarya province established a friendly relationship on August 28, 2002.

Sakarya, a province of Turkey, is located on the coast of the Black Sea. The river Sakarya feeds this beautiful location. The river creates a webbing of estuaries in the province, and its natural beauty is breathtaking.

Located in the Marmara Region, its adjacent provinces are Kocaeli to the west, Bilecik to the south, Bolu to the southeast, and Düzce to the east. The capital of Sakarya is Adapazarı.

It has an oceanic climate due to its close proximity to the Black Sea. The weather is never cold here, though winters have a fair share of rain. Summers are warm and comfortable.

Sakarya is situated on the Ankara-Istanbul Highway. It is well connected by rail, air and road. Istanbul is the nearest airport. The various tourist spots of Sakarya are also well connected by rail and road from Istanbul.

The city of Sakarya, one of the most important cities in Turkey due to its rapid growth and development, is also worthy of attention because of its natural beauty and cultural richness. It is one of the country's paradise-like spots with its sea, beaches, lakes, rivers, highlands, and thermal springs, along with traditional Ottoman districts such as Taraklı and Geyve, and historical relics inherited from the Byzantine and Ottoman eras that are worth witnessing.
