However the record label categorically stated they were not involved contrary to the credits on the music video. Universal Records however did mention that they were invited by Chinatown TV to help promote the song but the record label declined the offer. Statements supportive of China from various government officials including Philippine PresidentRodrigo Duterte, Foreign Secretary Teodoro Locsin Jr., Health SecretaryFrancisco Duque were also featured in the video.

Reception
As of July 2020, the music video of "Iisang Dagat" in YouTube has received more than 4,000 likes and at least 220,000 dislikes. Criticism of the video includes perception that the song as a propaganda supportive of the Chinese government's stance in the South China Sea disputes. Imelda Papin in response to backlash insists she is not a "traitor", says that she was not aware that the song is a "propaganda" and narrated on how she was approached by the Chinese embassy to perform a song on "unity" which serves as a tribute to cooperation of Chinese and Filipino front-liners against the COVID-19 pandemic. Former Senior Associate Justice Antonio Carpio, who played a key role in the 2016 South China Sea arbitration decided by the Permanent Court of Arbitration, connected the title of the song to the position of the Chinese government on the South China Sea disputes. Carpio says that song title is an allusion to the South China Sea and has an implied message that China owns the South China Sea. He said that the video is part of a larger effort of China to influence public opinion to make up for its failures at the early stage of the COVID-19 pandemic. Carpio attributed the disproportionate number of dislikes of "Iisang Dagat"'s YouTube music video as evidence that the move "boomeranged" on China making Filipinos "more angry at China". Jay Batongbacal, Director of the UP Institute for Maritime Affairs and Law of the Sea says that the video is an attempt to placate Filipino public opinion following recent diplomatic protests filed over China's continued activity to assert its territorial claims in the South China Sea taking advantage of countries' preoccupation in dealing with the COVID-19 pandemic. "Save Our Seas", a 2019 song by Vietnamese rapper Tu P, Filipino rapper Marx Sickmind, and Malaysian singer Mei Lee which is about the South China Sea dispute as well as "Isang Bangka", a Philippine Navy institutional song by The Band gained traction following the release of "Iisang Dagat".
