( CNN ) -- Singapore 's escalating dispute with its neighbor Indonesia over the naming of a warship has led to a series of tit-for-tat snubs involving the city 's airshow , which is being held this week . Lieutenant-General ( Retired ) Sjafrie Sjamsoeddin , Indonesia 's deputy defense minister , alongside the chiefs of the country 's three main military branches , will not be attending the Singapore Airshow , which begins Tuesday , in a form of diplomatic protest . Sjafrie also canceled other engagements in the city . The withdrawal comes after Singapore rescinded the invitations of around 100 members of Indonesia 's military hierarchy . The snub was a response to Indonesia 's decision to name a warship after two marines who were tried and convicted of blowing up a bank in Singapore in 1965 during the conflict known as the Konfrontasi , between Indonesia and Malaysia , of which Singapore was a part at the time . The attack killed three and injured 33 . The decision to name a naval frigate the KRI Usman Harun , after Sergeants Usman Haji Mohamed Ali and Harun Said , has angered the city-state , which says that it reflects a lack of sensitivity and respect for mutual ties . The marines were executed in Singapore . Their remains were repatriated and , the pair were lauded as heroes , as they were buried with full honors . The matter was thought to be put to bed when Singapore 's then-President Lee Kuan Yew scattered petals on the Indonesian soldiers ' graves in 1973 . `` I am disappointed with the Indonesian decision to name their new warship after the two convicted ex-marines , '' said Chan Chun Sing , Singapore 's Second Minister for Defence , said in an official Ministry release . `` I am also disappointed with the reactions of the Indonesian leaders who have spoken on this issue thus far . `` The [ Indonesian leaders ' ] statements reflected either a lack of sensitivity , a lack of care for the bilateral ties , or both . '' Indonesia has stuck by its naming decisions , with officials saying that the practice of naming naval vessels after heroes is commonplace . Chan added , `` I hope the Indonesian leaders will not sacrifice our bilateral relations , so carefully built up , to domestic politics or through carelessness . '' Indonesia 's defense ministry confirmed the officials ' non-attendance on Sunday , Defense News reported . `` The visit by senior TNI [ Indonesian National Armed Forces ] officers , military chiefs of staff and TNI commander to Singapore has been canceled , '' the ministry said a statement . The journal added that an Indonesian aerobatic team would still perform at the show . Despite differences , including protests against an annual forest burn conducted by the larger country , which affects air quality in Singapore , the two countries enjoy a full diplomatic relationship and have strong commercial ties . Indonesia is Singapore 's third-largest individual trading partner . The Singapore Airshow , set to be the biggest to date officially opened on Monday evening and events will run from February 11 to 16 .
