WASHINGTON (AP) — House Minority Leader Nancy Pelosi and six other Democrats left Washington on Thursday for a trip to China that will focus on national and cyber security, climate change and human rights.

"Our delegation travels to China seeking to expand cooperation between our nations in advancing economic growth and confronting the climate crisis that threatens our world," Pelosi said in a statement.

The lawmakers plan to meet with local government officials, students and other individuals.

Pelosi, the former House speaker, has been outspoken on the issue of human rights throughout her nearly 30 years in Congress. She last traveled to China in 2009.

Joining her on the trip were Reps. Jim McGovern of Massachusetts, Betty McCollum and Tim Walz of Minnesota, Joyce Beatty of Ohio and Alan Lowenthal and Ted Lieu of California.

The trip comes amid questions about Chinese hacking attempts on American corporate intellectual property.
