BEIJING - Seventeen journalists from European Union (EU) countries visited the disciplinary watchdog of the Communist Party of China (CPC) on Tuesday.

The journalists visited the news release hall and a selection of working areas of the CPC Central Commission for Discipline Inspection (CCDI) to get a better understanding of its daily work, according to a statement from the CCDI.

CCDI spokesman Cui Shaopeng and other officials held a discussion with the guests to answer their questions and exchange views on issues, such as how to supervise the use of power and deal with petitions.

The CCDI said it has always maintained a high-pressure crackdown on officials' corruption and insisted on punishment of both "tigers" and "flies," the words used by President Xi Jinping to describe high-ranking and low-level corrupt officials, according to the statement.

The CCDI also said it has established friendly relations with the anti-corruption organs of more than 80 countries and regions.

China was ratified to join the United Nations Convention Against Corruption in 2005 and is under the UN's review on the implementation of the convention, according to the CCDI.

The journalists expressed their appreciation for the visit, which lasted over three hours.
