The MFA spokesman said:
Prime Minister Lee Hsien Loong called United States President Donald Trump on 29 August 2017 to express his concern and sympathies over the loss of life and damage caused by Hurricane Harvey in Texas and Louisiana. PM Lee also said that Singapore was ready to assist in the disaster relief operations by deploying the Republic of Singapore Air Force's (RSAF) CH-47 Chinook helicopters from its Peace Prairie detachment in Grand Prairie, Texas. President Trump thanked PM Lee and accepted his offer of help.
President Trump and PM Lee also discussed the Democratic People's Republic of Korea's (DPRK) continued and deliberate provocations, including the latest ballistic missile launch on 29 August 2017. PM Lee said Singapore was deeply concerned and had issued a statement condemning this reckless action.
Both leaders also looked forward to their meeting in the White House in October 2017.
