Shortcomings

Despite its value, some concerns surround the MUN. These include occupying much of students' time and dilution of standards as MUN groups proliferate.

China hosts about 500 MUN events annually, says Tang Jie, chairman of the Ocean Conference at the BIMUN.

The increase of MUN bodies mean few conferences meet the high standards of academic writing, he says. And many documents, including backgrounders, lack originality. "And some delegates regard it as a dress party to socialize," he says.

Tang advises participants to sustain their enthusiasm about global citizenship, learn new things and work to make their voices heard.

A typical MUN event lasts only a few days, but its value can last over the long term.

Fang encourages participants to forge friendships and passion for international affairs that last beyond the events.

"I hope more students will consider diplomacy as a career option," he says.
