NUSA DUA, Indonesia, Nov 14 (Reuters) - U.S. President Joe Biden and Chinese President Xi Jinping engaged in blunt talks over Taiwan and North Korea on Monday in a three-hour meeting aimed at preventing strained U.S.-China ties from spilling into a new Cold War.

Amid simmering differences on human rights, Russia's invasion of Ukraine, and support of domestic industry, the two leaders pledged more frequent communications. U.S. Secretary of State Antony Blinken will travel to Beijing for follow-up talks.

"We're going to compete vigorously. But I'm not looking for conflict, I'm looking to manage this competition responsibly," Biden said after his talks with Xi on the sidelines of the G20 summit in Indonesia.

Beijing has long said it would bring the self-governed island of Taiwan, which it views as an inalienable part of China, under its control and has not ruled out the use of force to do so. It has frequently accused the United States in recent years of encouraging Taiwan independence.

In a statement after their meeting, Xi called Taiwan the "first red line" that must not be crossed in U.S.-China relations, Chinese state media said.

Biden said he sought to assure Xi that U.S. policy on Taiwan, which has for decades been to support both Beijing's 'One China' stance and Taiwan's military, had not changed.

He said there was no need for a new Cold War, and that he did not think China was planning a hot one.

"I do not think there's any imminent attempt on the part of China to invade Taiwan," he told reporters.

On North Korea, Biden said it was hard to know whether Beijing had any influence over Pyongyang weapons testing. "Well, first of all, it's difficult to say that I am certain that China can control North Korea," he said.

Biden said he told Xi the United States would do what it needs to do to defend itself and allies South Korea and Japan, which could be "maybe more up in the face of China" though not directed against it.

"We would have to take certain actions that would be more defensive on our behalf... to send a clear message to North Korea. We are going to defend our allies, as well as American soil and American capacity," he said.

Biden's national security adviser Jake Sullivan said before the meeting that Biden would warn Xi about the possibility of enhanced U.S. military presence in the region, something Beijing is not keen to see.
