Wang, who will arrive here from the Maldives, will meet President Gotabaya Rajapaksa, Prime Minister Mahinda Rajapaksa, and Foreign Minister G L Peiris during the visit, Foreign Secretary Jayanath Colombage said.
His visit marks the 65th anniversary of diplomatic ties between the two nations and the 70th anniversary of the Lanka-China Rubber Rice Pact.
Signed in 1952, the Rubber-Rice Pact was a trade agreement between Lanka and China under which Colombo supplied rubber to Beijing in exchange for rice, leading to the establishment of diplomatic relations and expansion of trade between the two nations.
The events marking the occasions will be held at the Chinese-built port city in central Colombo, one of the many mega infrastructure development projects supported by China since 2010.
Colombage said new Chinese investment opportunities might be sealed by Sri Lanka during the foreign minister's visit.
The relationship between the two countries has been under stress in recent months.
China protested against Sri Lanka's rejection of an organic fertilizer shipment which the local farmers and some experts claimed was contaminated.
The Sri Lankan commercial high court here blocked payment for it despite top-level interventions by China. The Chinese black-listed the Sri Lankan state bank for not honouring the payment.
Sri Lankan scientists had questioned the quality of the Chinese fertilizer consignment, saying that instead of helping, it could prove harmful to the crops.
However, on Friday, on the eve of Wang's visit, Sri Lanka's People's Bank released USD 6.9 million US to the Chinese company.
China's blacklisting of the Sri Lankan bank, and the public clash between officials on both sides, had come amid growing concerns over an acute agriculture crisis in Sri Lanka, following President Gotabaya Rajapaksa's decision in May last year to abruptly switch from chemical to organic fertilizers.
The decision triggered protests from farmers who said the fertilizer ban would result in a reduction in harvest, leading to a food crisis this year.
China in December suspended a project to install hybrid energy plants in three islands of Sri Lanka, citing ''security concern'' from a ''third party'', amid reports of India raising concern over its location.
In early 2021, India lodged a ''strong protest'' with Lanka on the award of the tender to the Chinese company for the construction of renewable energy power plants in Delft, Nagadeepa, and Analthivu.
The visit also happens at a time when Sri Lanka is facing its all-time worst foreign exchange crisis.
By December, the reserves position had plummeted to just one month's imports or a little over USD 1 billion.
However, by the end of the year, the Central Bank announced that the reserves position had improved and the cash realization was believed to have come from a previously agreed currency swap with China.
