The Chinese military deployed 71 aircraft and nine naval vessels around Taiwan on Sunday, the second day in a row that the People's Liberation Army has conducted massive drills near the island. 

It comes after Taiwan President Tsai Ing-wen returned this week from a trip to the United States, where she met with House Speaker Kevin McCarthy, R-Calif., and other lawmakers. 

Taiwan's Ministry of Defense tasked its air force, navy, and land-based missile systems to monitor the Chines aircraft, 45 of which crossed the median line of the Taiwan Strait, an unofficial buffer zone between the island and mainland China. 

Chinese state television said that the units carried out "simulated joint precision strikes on key targets on Taiwan island and the surrounding sea areas," according to Reuters.

China regularly dispatches aircraft and ships around Taiwan, though this weekend's drills were much larger than in recent months. 

Beijing was outraged at the meeting between McCarthy and Taiwan's president, responding by slapping sanctions on the Ronald Reagan Presidential Library, where the two leaders met, as well as the Hudson Institute for "providing a platform and convenience to Taiwan separatist activities."

Sen. Lindsey Graham, R-S.C., and other hawkish lawmakers have stepped up calls for the U.S. to commit to defending Taiwan in the event of an invasion by China

"The question for the Congress – should we have a defense agreement with the island of Taiwan? We don't, should we have one?" Graham told Fox News Sunday. "Yes, I'd be very much open to using U.S. forces to defend Taiwan, because it's in our national security interest to do so."

Rep. Mike Gallagher, R-Wisc., the Chairman of the House Select Committee on China, noted that Chinese President Xi Jinping "would like to reunify Taiwan with the mainland by force if necessary."

"The fact that the Chinese were throwing a temper tantrum about the Speaker of the House meeting with the democratically elected leader of Taiwan on American soil just shows you how sensitive they are," Gallagher told Fox News' Sunday Morning Futures. "We need to be moving heaven and earth to surge power out to the Indo-Pacific before it's too late, before we have another war on our hands."
