Three years after Malaysia Airlines Flight 370 vanished, searchers have found debris in the Indian Ocean believed to be from the doomed airliner. They have confirmed three pieces as certainly from the plane, while five others remain highly likely but inconclusive.
The first pieces of a US-built missile defense system designed to mitigate the threat of North Korean missiles arrived at the Osan Air Base in South Korea Monday night, according to the US military.
The announcement comes just a day after North Korea test-fired four ballistic missiles into the Sea of Japan, also known as the East Sea.
China has voiced opposition to the proposed placement of the military hardware known as the Terminal High Altitude Area Defense (THAAD) system, which it sees as a threat to its own security.
"We will firmly take necessary measures to preserve our own security interest, and the US and South Korea must bear the potential consequences," Ministry of Foreign Affairs spokesman Geng Shuang said Tuesday.
With North Korea upping the amount of missile and nuclear tests last year, the US and South Korea have publicly stressed the need to speed up the deployment of the technology.
It's designed to shoot down incoming missiles that threaten civilian populations, akin to shooting a bullet with another bullet in simple terms, experts say.
"Continued provocative actions by North Korea, to include yesterday's launch of multiple missiles, only confirm the prudence of our alliance decision last year to deploy THAAD to South Korea," Adm. Harry Harris, commander, US Pacific Command, said in a news release.
The decision to deploy THAAD in South Korea was made in July of last year, and US President Donald Trump's administration has said it's committed to following through.
US Secretary of Defense James Mattis and South Korean Defense Secretary Han Min-koo spoke over the phone last week and agreed that THAAD should be deployed "ASAP."
China has long opposed the deployment of the defense system so close to its own borders and has called on the US and South Korea to stop the deployment.
One concern is that THAAD's advanced radar system could be used to spy on China's activities, rather than monitor incoming missiles from North Korea, according to Mark Tokola of the Korean Economic Institute of America.
China also worries THAAD would undermine its ability to respond to an attack on its own soil, says Tokola, a former deputy chief of mission at the US embassy in Seoul.
Beijing's displeasure has reportedly been felt by South Korean businesses, particularly Lotte, the South Korean conglomerate which signed off a land swap deal with the government to provide a site for the THAAD launch systems in late February.
In a fiercely-worded commentary published by China's official news agency, Xinhua, said the Lotte board would "hurt the Chinese people" and the "consequences could be severe" if it went ahead.
"Lotte stands to lose Chinese customers and the Chinese market. That would be a very large slice out of their business pie," said the commentary, which did not carry a byline.
The South Korean government said last week it believed Chinese authorities had told travel agencies in Beijing to stop selling trips to South Korea, intensifying fears of a trade war between the neighbors.
The Chinese government, however, denied any knowledge of such an order.
If Beijing did choose to retaliate through trade, it could make significant dent. China is South Korea's largest trading partner, with the latter exporting up to $142 billion each year to the country.
Almost half of the 17 million people who visited South Korea last year were Chinese, according to data from the Korea Tourism Organization.
South Korea itself is split on its support for THAAD. The military wants it, the residents who will live nearby the system don't and opposition parties say it should be debated and voted on within parliament once the current political uncertainty is resolved.
South Korean President Park Geun-hye is on trial after being impeached for her involvement in a corruption scandal.
"Under the circumstances, such a critical decision should be handled by the incoming government which will have full legitimacy and authorization," says Song Young-gil from the Democratic Party of Korea.
The system isn't a panacea that would completely shield the US and its allies from the North Korean missile threat.
It's "aimed solely at defending South Korea against missiles from North Korea," according to US Forces in Korea.
The system could be overwhelmed if North Korea were to launch a series of missiles simultaneously and it's not effective against submarine-launched ballistic missiles launched from south, east or west of lower South Korea, according to a report from the North Korea monitoring group 38 North.

THAAD can detect and track targets within a range of about 1,000 kilometers, the report said, which means it may not stop a potential intercontinental ballistic missile (ICBM).
North Korean leader Kim Jong Un said in January that his country is in the final stages of developing an ICBM, which could reach the west coast of the United States.
But President Trump vowed that "it won't happen" in a tweet prior to his inauguration.

South Korea's Constitutional Court has upheld a decision by the country's National Assembly to impeach President Park Geun-hye.
The group of lawyers has so far recruited 474 plaintiffs from among the almost 10,000 artists on the list.
The first South Korean president to be impeached, Park Geun-hye spent both her youth and later years in the Blue House.
When Brian and Jeri Wilson brought home their 10-year-old adopted son Jason, formerly known as JiaJia, for the first time last year, the couple quickly realized they needed to move.
“These racial gaps in political participation mean that not all Californians are being heard."
People of color are growing accustomed to imminent danger.
South Korea's Park Geun-hye became the country's first president to be ousted by impeachment after judges on Friday upheld a motion to dismiss her.
The Ayala Corporation has made a push to invest in businesses that could play a major role in shaping the country's "social infrastructure."
The United States said "all options are on the table" to deal with North Korea and dismissed China's suggestion of a "dual suspension."
