(CNN) Federal prosecutors have filed charges against a woman carrying Chinese passports who they accused of illegally entering President Donald Trump's Mar-a-Lago club in Florida in late March.

Yujing Zhang claimed a friend had asked her to fly from Shanghai to the club to try to speak to a member of Trump's family about economic relations between the US and China, according to the complaint.

Zhang initially gained access to the property on March 30 through an apparent miscommunication with members of Mar-a-Lago security.

She told a US Secret Service agent at the entrance she was there to "go to the pool," and produced two passports, according to the complaint. Mar-a-Lago security subsequently admitted her.

But staff quickly became suspicious when she didn't know where she wanted to go inside the property. She told a receptionist she was there to attend a non-existent "United Nations Chinese American Association" event that evening.
