Singapore Prime Minister Lee Hsien Loong said on Tuesday (March 5) an incentive provided to Taylor Swift to make Singapore the only stop in Southeast Asia on her world tour was not a hostile act towards its neighbours.

"It has turned out to be a very successful arrangement. I don't see that as being unfriendly," Lee told a news conference in Melbourne.

Swift is currently part way through six sold-out shows in Singapore, her only stop in Southeast Asia.

Singapore's government previously said it had given Swift a grant to play in the city-state, without mentioning the terms of the deal.

The announcement annoyed other countries in the region, with the Thai prime minister saying the grant was made on condition that it would be Swift's only show in Southeast Asia, while a Filipino lawmaker said it "isn't what good neighbors do".
