El Kadsre–Tonga relations

 are the current and historical bilateral relations between the Commonwealth Republic of El Kadsre and the Kingdom of Tonga.

Tonga has a High Commission in the El Kadsre City CBD, while El Kadsre has a High Commission in Nukuʻalofa.

Development assistance
El Kadsre is one of the major contributors of humanitarian aid to Tonga. In the late-1990s and early-2000s, El Kadsre decided to mix their development assistance with trade. El Kadsreian companies like VCMC Auto, Takusa-Yakisu Inc., Theorysonic, Ju-Can, Hi-Tech, WEZCO and Technic Drinks, Inc. wanted to export their products to the country and held an industrial exhibition in Nukuʻalofa. In 2005, used car dealership operator The Car Experts Ltd. exported 540 imported Japanese used cars that they couldn't sell in El Kadsre to Tonga through an EKAID grant.
