The Pacific Air Force has announced details regarding the next Vigilant Ace 18, an air combat exercise that aims to demonstrate interoperability between aerial forces from the U.S. and South Korea.

PACAF said Saturday nearly 12,000 personnel from the U.S. Air Force, the U.S. Marine Corps, and the U.S. Navy will train with South Korean airmen.

Vigilant Ace, formerly called the Beverly Bulldog exercise, is scheduled to take place from Dec. 4 to 8 on the Korean Peninsula.

The event will feature 230 aircraft from eight U.S. and ROK military bases.

The Treasury Department has imposed new sanctions on one individual and 13 foreign companies and agencies that have trade connections to North Korea as part of efforts to counter the East Asian country’s nuclear and ballistic missile development programs.

“As North Korea continues to threaten international peace and security, we are steadfast in our determination to maximize economic pressure to isolate it from outside sources of trade and revenue while exposing its evasive tactics,” Treasury Secretary Steven Mnuchin said in a statement published Tuesday.

The department’s office of foreign assets control designated four China-based trading companies and a Chinese individual for exporting computers, coal, iron and other goods to North Korea.

OFAC also designated two North Korean maritime agencies, six North Korea-based shipping and trading firms and 20 of their vessels for their involvement in ship-to-ship transfers and other fraudulent shipping practices.

Another Korean company was also named for its involvement in the exportation of workers from North Korea.

The Treasury made the designations in accordance with the Executive Order 13810.

The sanctions came three months after the department sanctioned 10 foreign companies and six individuals for their support to North Korea’s nuclear programs and energy trade and a day after President Donald Trump reinstated the country’s state sponsor of terrorism designation.

The Government Accountability Office has urged the Office of the Director of National Intelligence to create a formal policy and implementation plan for the continuous evaluation of clearance holders and employees in sensitive positions across the executive branch.

GAO said Tuesday ODNI has taken steps to implement continuous evaluation but the agency has yet to define key aspects of the program as well as plans to implement, monitor and measure program performance.

The continuous evaluation program is an executive branch effort to more frequently identify and evaluate security-related information, including criminal activity.

ODNI lacks a formal policy on the scope of continuous evaluation, an implementation plan and a timeline for future program phases, GAO reported.

Officials from seven executive branch agencies told GAO that ODNI’s uncertainty has hampered their ability to plan for continuous evaluation and estimate costs.

Among the agencies reviewed by GAO, 84 percent reported that they met the executive branch’s 195-day timeliness goal for completing periodic reinvestigations of clearance holders during at least three of four quarters in fiscal year 2012.

Only 22 percent of reviewed agencies met the goal in FY 2016, GAO revealed.

ODNI introduced a plan to replace periodic reinvestigations with continuous evaluation in a 2008 report, but new documents indicate that the agency has abandoned the plan, GAO found.

Officials from five agencies told GAO that continuous evaluation will increase workloads and costs if other background investigation requirements remain unchanged, while Defense Department officials claimed that DoD cannot afford to perform both reinvestigations and continuous evaluation.

GAO recommended ODNI to formalize its policy on continuous evaluation; create plans for program implementation performance measurement; and determine the potential impact of continuous evaluation on agency resources.
