German Chancellor Angela Merkel says she discussed human rights and other sensitive issues with China's leaders in Beijing Monday.
Ms. Merkel met separately with Chinese Premier Wen Jiabao and President Hu Jintao on the second day of her visit to China.
After meeting Mr. Hu, the German chancellor said she pointed out that China will face increasing global scrutiny in the run up to next year's Beijing Olympics.
In her talks with Mr. Wen, Ms. Merkel says she urged China to respect international norms as its economy develops. Beijing has faced criticism from Germany and other countries for recent scandals involving tainted Chinese exports.
Ms. Merkel also called on China's leaders to do more to protect intellectual property rights and combat climate change.
Mr. Wen says China wants to fight pollution but faces difficulties because it lacks the resources of rich countries such as Germany.
Mr. Wen also says China is "gravely concerned" by a report in German magazine "Der Spiegel" that Chinese hackers have penetrated German government computers. He says China will take "firm action" to prevent hacking attacks.
Ms. Merkel did not say if she discussed the crisis in Sudan's Darfur region with her Chinese hosts. Before arriving in China, she said she would raise the issue of Beijing's relationship with Sudan's government.
Human rights activists say China should use its economic ties with Sudan to pressure the government into ending the violence in Darfur.
Ms. Merkel arrived in Beijing Sunday. She departs for Japan Wednesday.
