SAN FRANCISCO, Oct. 28 (Xinhua) -- Award-winning films have been screened to boost cultural exchanges between China and the United States at the 2019 Davis International Film Festival (DIFF) which ended Sunday night in Northern California.

Nearly 90 films from around the world were accepted for competition at this year's film festival, DIFF Chairperson Wan Ning told Xinhua.

The film festival gave special focus to cultural exchanges between youths from different countries by setting up a youth screenplay competition, Wan said.

Fu Rong Du, produced by Xiaoxiang Film Studio of central China's Hunan province, won the title of Best Chinese Film.

The full-length American movie Kayla, which told a story of a three-generation family struggling with cultural conflict of Chinese and American values and beliefs, was awarded Best English Feature Film.

Kayla Bohan, a fourth-grade, nine-year-old girl from an elementary school in Los Angeles, Southern California, won Best Child Actress for starring as the leading actress in Kayla.

"I learned that if you have a big role, that's really good, but it also takes a lot of responsibility," Bohan said at the awarding ceremony.

"I hope that the spirit of my character will encourage people all over the world. I want to pass the message of being kind, strong and brave because this world is full of magic and hope," she added.

Robert Rustad, a preliminary juror of the film festival, told Xinhua that he was impressed by the craftsmanship of the films from around the world.

"Each year all of the filmmakers keep raising the bar, and we had lots of great filmmakers from America, China, Iran and all over the world," he said.

Cultural and art exchanges like DIFF will greatly benefit both China and the United States, with more cooperation in the film industry going on in the future, Rustad said.
