One side of the coin marks the Chinese party's anniversary while the other celebrates 65 years of diplomatic ties between the two nations
Sri Lanka on Wednesday issued its most expensive gold coin ever to celebrate the 100th anniversary of the Chinese Communist Party, underscoring the close ties between the countries.
The commemorative 1,000-rupee coin will be sold for 222,000 rupees from Monday, the Central Bank of Sri Lanka said.
"The coins have been issued at the request of the government of Sri Lanka as an accolade for long-standing friendship and mutual trust between the two countries," the bank said.
Sri Lanka has increasingly turned to China for financing and diplomatic support in recent years, prompting India and the United States to express concern.
One side of the 12-gram coin marks the Chinese party's anniversary while the other celebrates 65 years of diplomatic ties between the two nations and depicts a Colombo theatre built with Chinese financing.
Sri Lanka released its last gold coin to mark 50 years of independence from Britain in 1998, but that one was only two thirds the weight of the Chinese anniversary coin.
Colombo had also never before issued a coin to commemorate a political party.
Beijing has made increasing trade and diplomatic inroads in South Asia in recent years.
In 2017, unable to repay a huge Chinese loan, Sri Lanka allowed China Merchants Port Holdings to take over Hambantota port, which straddles the world's busiest east-west shipping route, on a 99-year lease.
